laravel carbon 统计七天数据

        $where = ['recycle_user_id' => Auth::user()->user_id];

        $today = [
            Carbon::Now()->startOfDay(),
            Carbon::Now()->endOfDay()
        ];
        $seven = [

        $month = [
            Carbon::Now()->subDays(30),
            Carbon::Now()->startOfDay(),
        ];

        $data = \DB::table('order')->select([
            \DB::raw('sum(case when status = "create" then 1 else 0 end) as create_count '),
            \DB::raw('sum(case when status = "finish" then 1 else 0 end) as finish_count '),

laravel + vue实现的数据统计绘图（今天、7天、30天数据）

前言

本文主要是按照时段统计今天、7天、30天的数据，利用laravel+vue实现的，下面话不多说了，来一起看看详细的介绍吧

效果图：

1. 前端vue

使用vue-highcharts

<highcharts :options="options"></highcharts>

data() {
 return {
  options: {
  title: {
   text: ''''
  },
  xAxis: {
   categories: []
  },
  yAxis: {
   title: {
   text: ''''
   },
   plotLines: [{
   value: 0,
   width: 1,
   color: ''#808080''
   }]
  },
  legend: {
   layout: ''horizontal'',
   align: ''center'',
   verticalAlign: ''bottom'',
   borderWidth: 0
  },
  credits: {
   enabled: false // 去掉highcharts商标
  },
  series: []
  }
 }
 },

请求数据处理：

getTimingHistoryAct(time) {
  getTimingHistory(time).then(response => {
  const curHour = new Date().getHours()
  const hoursArr = []
  const dayArr = []
  const seriesData = []
  switch (time) {
   case 1:
   seriesData.length = 0
   for (let i = 0; i <= curHour; i++) {
    hoursArr.push(i < 10 ? ''0'' + i : '''' + i)
    seriesData[i] = 0
   }
   this.options.xAxis.categories = hoursArr.map(x => x + '':00'')
   response.data.forEach(record => {
    const index = hoursArr.indexOf(record.hour)
    if (index > -1) {
    seriesData[index] = record.count
    }
   })
   break
   case 7:
   seriesData.length = 0
   for (let i = 0; i < 7; i++) {
    const ymd = new Date(new Date() - 24 * 60 * 60 * 1000 * i).toLocaleString().split('' '')[0]
    const ymdarr = ymd.split(''/'')
    if (ymdarr[1] * 1 < 10) {
    ymdarr[1] = ''0'' + ymdarr[1]
    }
    if (ymdarr[2] * 1 < 10) {
    ymdarr[2] = ''0'' + ymdarr[1]
    }
    seriesData[i] = 0
    dayArr.unshift(ymdarr.join(''-''))
   }
   this.options.xAxis.categories = dayArr.map(x => x.substr(5))
   response.data.forEach(record => {
    const index = dayArr.indexOf(record.date)
    if (index > -1) {
    seriesData[index] = record.count
    }
   })
   break
   case 30:
   // 同7天
   break
  }
  this.options.series = [{
   name: ''商品点击'',
   data: seriesData
  }]
  })
 },

2. 后台laravel

      break;
    case ''7'':
      $data = StatsPlanClick::where(''created_at'',''<'', Carbon::now())->where(''created_at'',''>'', Carbon::today()->subDays(7))->select([DB::raw(''DATE(created_at) as date''), DB::raw(''COUNT("*") as count'')])->groupBy(''date'')->get();
      break;

      $data = StatsPlanClick::where(''created_at'',''<'', Carbon::now())->where(''created_at'',''>'', Carbon::today()->subDays(30))->select([DB::raw(''DATE(created_at) as date''), DB::raw(''COUNT("*") as count'')])->groupBy(''date'')->get();
      break;
    default:
      # code...
      break;
  }
  return $this->successWithData($data);
}

12 echo $yesterday;                         // 2015-03-25 00:00:00

建立特定日期的時間

 1 <?php
 2  
 3 use Carbon\Carbon;
 4  
 5 $timezone = ''Asia/Taipei'';
 6  
 7 // 從「年月日」建立
 8 Carbon::createFromDate($year, $month, $day, $timezone);

11 Carbon::createFromTime($hour, $minute, $second, $timezone);
12  
13 // 從完整的「年月日時分秒」建立
14 Carbon::create($year, $month, $day, $hour, $minute, $second, $timezone);

19  
20 // 從時間戳記建立
21 echo Carbon::createFromTimeStamp(-1)->toDateTimeString();                        // 1969-12-31 18:59:59
22 echo Carbon::createFromTimeStamp(-1, ''Europe/London'')->toDateTimeString();       // 1970-01-01 00:59:59
23 echo Carbon::createFromTimeStampUTC(-1)->toDateTimeString();                     // 1969-12-31 23:59:59

轉換日期

 1 <?php
 2  
 3 use Carbon\Carbon;
 4  
 5 // 透過文字移動日期
 6 $knownDate = Carbon::create(2001, 5, 21, 12);          // create testing date

介绍

Carbon类是从PHP DateTime类继承的。

<?php
namespace Carbon;

class Carbon extends \DateTime { // code here } 

您可以从上面的代码片段中看到Carbon类是在Carbon名称空间中声明的。您需要导入名称空间以使用Carbon，而不必每次都提供其完全限定名称。

use Carbon\Carbon;

本文档中的示例将假定您以这种方式导入了Carbon名称空间的类。

我们还提供了CarbonImmutable类，扩展了DateTimeImmutable。两种类都可以使用相同的方法，但是在Carbon实例上使用修饰符时，它会修改并返回相同的实例，在CarbonImmutable上使用它时，它将返回具有新值的新实例。

$mutable = Carbon::now();
$immutable = CarbonImmutable::now();
$modifiedMutable = $mutable->add(1, ''day''); $modifiedImmutable = CarbonImmutable::now()->add(1, ''day''); var_dump($modifiedMutable === $mutable); // bool(true) var_dump($mutable->isoFormat(''dddd D'')); // string(11) "Saturday 15" var_dump($modifiedMutable->isoFormat(''dddd D'')); // string(11) "Saturday 15" // So it means $mutable and $modifiedMutable are the same object // both set to now + 1 day. var_dump($modifiedImmutable === $immutable); // bool(false) var_dump($immutable->isoFormat(''dddd D'')); // string(9) "Friday 14" var_dump($modifiedImmutable->isoFormat(''dddd D'')); // string(11) "Saturday 15" // While $immutable is still set to now and cannot be changed and // $modifiedImmutable is a new instance created from $immutable // set to now + 1 day. $mutable = CarbonImmutable::now()->toMutable(); var_dump($mutable->isMutable()); // bool(true) var_dump($mutable->isImmutable()); // bool(false) $immutable = Carbon::now()->toImmutable(); var_dump($immutable->isMutable()); // bool(false) var_dump($immutable->isImmutable()); // bool(true) 

该库还提供CarbonInterface接口扩展DateTimeInterface和JsonSerializable， CarbonInterval类扩展DateInterval， CarbonTimeZone类扩展DateTimeZone 和CarbonPeriod类polyfills DatePeriod。

Carbon具有从基本DateTime类继承的所有功能。这种方法使您可以访问基本功能，例如 Modify， Format或 diff。

现在，让我们看看这个文档有多酷。点击下面的代码：

$dtToronto = Carbon::create(2012, 1, 1, 0, 0, 0, ''America/Toronto''); $dtVancouver = Carbon::create(2012, 1, 1, 0, 0, 0, ''America/Vancouver''); // Try to replace the 4th number (hours) or the last argument (timezone) with // Europe/Paris for example and see the actual result on the right hand. // It''s alive! echo $dtVancouver->diffInHours($dtToronto); // 3 // Now, try to double-click on "diffInHours" or "create" to open // the References panel. // Once the references panel is open, you can use the search field to // filter the list or click the (<) button to close it. 

一些示例是静态代码段，其他一些示例是可编辑的（当有右上角的展开按钮时）。您也可以单击此按钮在新标签页中打开代码段。您可以在静态和动态示例中双击方法名称。

实例化

有几种不同的方法可用于创建Carbon的新实例。首先有一个构造函数。它会覆盖父构造函数，因此您最好阅读PHP手册中的第一个参数，并了解其接受的日期/时间字符串格式。希望您会发现自己很少使用构造函数，而是依靠显式的静态方法来提高可读性。

$carbon = new Carbon();                  // equivalent to Carbon::now()
$carbon = new Carbon(''first day of January 2008'', ''America/Vancouver''); echo get_class($carbon); // ''Carbon\Carbon'' $carbon = new Carbon(new DateTime(''first day of January 2008''), new DateTimeZone(''America/Vancouver'')); // equivalent to previous instance 

您会在上面注意到timezone（2nd）参数是作为字符串而不是\DateTimeZone 实例传递的。所有DateTimeZone参数都得到了增强，因此您可以将DateTimeZone实例，字符串或整数偏移量传递给GM​​T，并将为您创建时区。在下一个示例中再次显示了该示例，该示例还介绍了该now()功能。

$now = Carbon::now(); // will use timezone as set with date_default_timezone_set
// PS: we recommend you to work with UTC as default timezone and only use
// other timezones (such as the user timezone) on display

$nowInLondonTz = Carbon::now(new DateTimeZone(''Europe/London'')); // or just pass the timezone as a string $nowInLondonTz = Carbon::now(''Europe/London''); echo $nowInLondonTz->tzName; // Europe/London echo "\n"; // or to create a date with a custom fixed timezone offset $date = Carbon::now(''+13:30''); echo $date->tzName; // +13:30 echo "\n"; // Get/set minutes offset from UTC echo $date->utcOffset(); // 810 echo "\n"; $date->utcOffset(180); echo $date->tzName; // +03:00 echo "\n"; echo $date->utcOffset(); // 180 

如果您真的喜欢您的可变方法调用，并在使用构造函数时对多余的行或丑陋的括号感到沮丧，那么您会喜欢这种parse方法。

echo (new Carbon(''first day of December 2008''))->addWeeks(2);     // 2008-12-15 00:00:00 echo "\n"; echo Carbon::parse(''first day of December 2008'')->addWeeks(2); // 2008-12-15 00:00:00 

传递给Carbon::parse或的字符串new Carbon可以表示相对时间（下一个星期日，明天，下个月的第一天，去年）或绝对时间（2008年12月的第一天，2017-01-06）。您可以使用来测试字符串是否会产生相对日期或绝对日期Carbon::hasRelativeKeywords()。

$string = ''first day of next month'';
if (strtotime($string) === false) { echo "''$string'' is not a valid date/time string."; } elseif (Carbon::hasRelativeKeywords($string)) { echo "''$string'' is a relative valid date/time string, it will returns different dates depending on the current date."; } else { echo "''$string'' is an absolute date/time string, it will always returns the same date."; }

伴随而来的是now()，还存在其他一些静态实例化助手来创建众所周知的实例。真正注意到这里的唯一的事情就是today()，tomorrow()和 yesterday()，除了如预期表现，都接受一个时区参数，每个人都有自己的时间值设置为00:00:00。

$now = Carbon::now();
echo $now;                               // 2020-02-14 16:05:16
echo "\n"; $today = Carbon::today(); echo $today; // 2020-02-14 00:00:00 echo "\n"; $tomorrow = Carbon::tomorrow(''Europe/London''); echo $tomorrow; // 2020-02-15 00:00:00 echo "\n"; $yesterday = Carbon::yesterday(); echo $yesterday; // 2020-02-13 00:00:00 

下一组静态助手是createXXX()助手。大多数静态create 函数允许您根据需要提供任意数量的参数，并为所有其他参数提供默认值。通常，默认值为当前日期，时间或时区。较高的值将适当地换行，但无效的值将引发InvalidArgumentException带有提示信息的。该消息是从DateTime :: getLastErrors（） 调用获得的。

$year = 2000; $month = 4; $day = 19; $hour = 20; $minute = 30; $second = 15; $tz = ''Europe/Madrid''; echo Carbon::createFromDate($year, $month, $day, $tz)."\n"; echo Carbon::createMidnightDate($year, $month, $day, $tz)."\n"; echo Carbon::createFromTime($hour, $minute, $second, $tz)."\n"; echo Carbon::createFromTimeString("$hour:$minute:$second", $tz)."\n"; echo Carbon::create($year, $month, $day, $hour, $minute, $second, $tz)."\n"; 

createFromDate()将默认为现在时间。createFromTime()将日期默认为今天。create()将把任何null参数默认为当前各自的值。和以前一样， $tz默认值是当前时区，否则可以是DateTimeZone实例，也可以只是一个字符串时区值。唯一的特殊情况是，create()对于缺少的参数，该参数的最小值为默认值，但在显式传递时，默认值为当前值null。

$xmasThisYear = Carbon::createFromDate(null, 12, 25);  // Year defaults to current year $Y2K = Carbon::create(2000, 1, 1, 0, 0, 0); // equivalent to Carbon::createMidnightDate(2000, 1, 1) $alsoY2K = Carbon::create(1999, 12, 31, 24); $noonLondonTz = Carbon::createFromTime(12, 0, 0, ''Europe/London''); $teaTime = Carbon::createFromTimeString(''17:00:00'', ''Europe/London''); try { Carbon::create(1975, 5, 21, 22, -2, 0); } catch(InvalidArgumentException $x) { echo $x->getMessage(); } // minute must be between 0 and 99, -2 given // Be careful, as Carbon::createFromDate() default values to current date, it can trigger overflow: // For example, if we are the 15th of June 2020, the following will set the date on 15: Carbon::createFromDate(2019, 4); // 2019-04-15 // If we are the 31th of October, as 31th April does not exist, it overflows to May: Carbon::createFromDate(2019, 4); // 2019-05-01 // That''s why you simply should not use Carbon::createFromDate() with only 2 parameters (1 or 3 are safe, but no 2) 

创建异常会在此类负值上发生，但不会在溢出时发生，要在溢出时获取异常，请使用 createSafe()

echo Carbon::create(2000, 1, 35, 13, 0, 0); // 2000-02-04 13:00:00 echo "\n"; try { Carbon::createSafe(2000, 1, 35, 13, 0, 0); } catch (\Carbon\Exceptions\InvalidDateException $exp) { echo $exp->getMessage(); } // day : 35 is not a valid value.

注1：2018-02-29也会产生例外，而2020-02-29不会例外，因为2020年是a年。

注意2：Carbon::createSafe(2014, 3, 30, 1, 30, 0, ''Europe/London'')也会产生一个例外，因为此时间以夏令时为单位（以小时为单位）。

注意3：PHP原生API允许考虑0之间有一个年份-1 ，1即使它与公历无关。因此，小于1的年份会使用引发异常createSafe。检查 isValid（）是否检测到0年。

Carbon::createFromFormat($format, $time, $tz);

createFromFormat()主要是基本php函数DateTime :: createFromFormat的包装。再次不同的是$tz参数可以是DateTimeZone实例或字符串时区值。另外，如果格式存在错误，此函数将调用该DateTime::getLastErrors()方法，然后将InvalidArgumentException带有错误的a作为消息抛出。

echo Carbon::createFromFormat(''Y-m-d H'', ''1975-05-21 22'')->toDateTimeString(); // 1975-05-21 22:00:00

最后三个create函数用于处理unix时间戳。第一个将创建一个与给定时间戳相等的Carbon实例，并将设置时区或将其默认为当前时区。第二个createFromTimestampUTC()是，不同之处在于，时区将保持UTC（GMT），其行为与UTC相同，Carbon::parse(''@''.$timestamp) 但我只是更明确了一点。第三个（createFromTimestampMs()）接受以毫秒为单位的时间戳，而不是秒。也可以使用负时间戳。

echo Carbon::createFromTimestamp(-1)->toDateTimeString();                                  // 1969-12-31 23:59:59
echo Carbon::createFromTimestamp(-1, ''Europe/London'')->toDateTimeString(); // 1970-01-01 00:59:59 echo Carbon::createFromTimestampUTC(-1)->toDateTimeString(); // 1969-12-31 23:59:59 echo Carbon::createFromTimestampMs(1)->format(''Y-m-d\TH:i:s.uP T''); // 1970-01-01T00:00:00.001000+00:00 UTC echo Carbon::createFromTimestampMs(1, ''Europe/London'')->format(''Y-m-d\TH:i:s.uP T''); // 1970-01-01T01:00:00.001000+01:00 BST 

您还可以创建copy()现有Carbon实例的。如预期的那样，日期，时间和时区值都将复制到新实例。

$dt = Carbon::now();
echo $dt->diffInYears($dt->copy()->addYear());  // 1 // $dt was unchanged and still holds the value of Carbon:now() 

您可以使用nowWithSameTz()现有的Carbon实例在同一时区现在获取一个新实例。

$meeting = Carbon::createFromTime(19, 15, 00, ''Africa/Johannesburg''); // 19:15 in Johannesburg echo ''Meeting starts at ''.$meeting->format(''H:i'').'' in Johannesburg.''; // Meeting starts at 19:15 in Johannesburg. // now in Johannesburg echo "It''s ".$meeting->nowWithSameTz()->format(''H:i'').'' right now in Johannesburg.''; // It''s 18:05 right now in Johannesburg. 

最后，如果您发现自己\DateTime从另一个库继承实例，请不要担心！您可以Carbon通过友好的instance()方法创建实例。或者使用更加灵活的方法make()，该方法可以从DateTime，Carbon或字符串返回新的Carbon实例，否则它仅返回null。

$dt = new \DateTime(''first day of January 2008''); // <== instance from another API
$carbon = Carbon::instance($dt); echo get_class($carbon); // ''Carbon\Carbon'' echo $carbon->toDateTimeString(); // 2008-01-01 00:00:00 

Carbon 2（需要PHP> = 7.1）完美支持微秒。但是，如果您使用Carbon 1和PHP <7.1，请阅读我们 有关部分微秒支持的部分。

是否曾经需要遍历某些日期来查找最早或最新的日期？不知道将初始最大值/最小值设置为什么？现在有两个帮助程序使您的决定变得简单：

echo Carbon::maxValue();                               // ''9999-12-31 23:59:59''
echo Carbon::minValue();                               // ''0001-01-01 00:00:00''

最小值和最大值主要取决于系统（32或64位）。

对于32位OS系统或32位版本的PHP（您可以使用来在PHP中进行检查PHP_INT_SIZE === 4），最小值为0-unix-timestamp（1970-01-01 00:00:00），最大值为常数给出的时间戳PHP_INT_MAX。

对于64位OS系统和64位版本的PHP，最小值为01-01-01 00:00:00，最大值为9999-12-31 23:59:59。甚至可以使用负数年份，最大为-9999，但是请注意，由于PHP中存在年份0，但在公历中不存在年份，因此某些操作可能无法获得准确的结果。

本土化

通过Carbon 2，本地化发生了很大变化，支持749个新语言环境，我们现在嵌入了语言环境格式，日期名称，月份名称，序数后缀，子午线，星期开始等等。尽管Carbon 1提供了部分支持并依赖于IntlDateFormatter类和语言包等第三方进行高级翻译，但您现在可以从广泛的国际化支持中受益。您还在使用Carbon 1吗？我希望您会考虑升级，版本2确实具有很酷的新功能。否则，您仍然可以通过单击此处阅读本地化的版本1文档。

从2.9.0版开始，您可以轻松自定义翻译：

// we recommend to use custom language name/variant
// rather than overriding an existing language
// to avoid conflict such as "en_Boring" in the example below:
$boringLanguage = ''en_Boring''; $translator = \Carbon\Translator::get($boringLanguage); $translator->setTranslations([ ''day'' => '':count boring day|:count boring days'', ]); // as this language starts with "en_" it will inherit from the locale "en" $date1 = Carbon::create(2018, 1, 1, 0, 0, 0); $date2 = Carbon::create(2018, 1, 4, 4, 0, 0); echo $date1->locale($boringLanguage)->diffForHumans($date2); // 3 boring days before $translator->setTranslations([ ''before'' => function ($time) { return ''[''.strtoupper($time).'']''; }, ]); echo $date1->locale($boringLanguage)->diffForHumans($date2); // [3 BORING DAYS] 

您可以通过以下方式使用后备语言环境locale()：

\Carbon\Translator::get(''xx'')->setTranslations([
    ''day'' => '':count Xday'',
]);
\Carbon\Translator::get(''xy'')->setTranslations([
    ''day'' => '':count Yday'', ''hour'' => '':count Yhour'', ]); $date = Carbon::now()->locale(''xx'', ''xy'', ''es'')->sub(''3 days 6 hours 40 minutes''); echo $date->ago([''parts'' => 3]); // hace 3 Xday 6 Yhour 40 minutos 

在上面的示例中，它将尝试先在“ xx”中查找翻译，然后在“ xy”中查找缺失的翻译，然后在“ es”中查找，因此在这里，您会从“ xx”获得“ Xday”，从“ xy”，“ es”中的“ hace”和“ minutos”。

请注意，Carbon::setTranslator($custom)只要给定翻译器实现，您也可以使用其他翻译器Symfony\Component\Translation\TranslatorInterface。你可以使用得到全局默认的转换Carbon::getTranslator()（以及Carbon::setFallbackLocale($custom) 和Carbon::getFallbackLocale()回退区域，setFallbackLocale可以被多次获得多个后备语言环境），但这些方法将在全球范围改变行为（包括第三方库，你可以在你的应用程序），可能会导致意外结果。如上例所示，您应该使用自定义语言环境自定义翻译。

Carbon嵌入了扩展Symfony \ Component \ Translation \ Translator的默认转换器。 您可以在此处检查我们添加到其中的方法。

因此，对于一个区域的支撑formatLocalized，吸气如localeMonth，localeDayOfWeek 短的变体是由安装在操作系统语言环境驱动。对于其他翻译，Carbon社区在内部为它提供了支持。您可以检查以下方法支持什么：

echo implode('', '', array_slice(Carbon::getAvailableLocales(), 0, 3)).''...''; // aa, aa_DJ, aa_ER... // Support diff syntax (before, after, from now, ago) var_dump(Carbon::localeHasDiffSyntax(''en'')); // bool(true) var_dump(Carbon::localeHasDiffSyntax(''zh_TW'')); // bool(true) // Support 1-day diff words (just now, yesterday, tomorrow) var_dump(Carbon::localeHasDiffOneDayWords(''en'')); // bool(true) var_dump(Carbon::localeHasDiffOneDayWords(''zh_TW'')); // bool(true) // Support 2-days diff words (before yesterday, after tomorrow) var_dump(Carbon::localeHasDiffTwoDayWords(''en'')); // bool(true) var_dump(Carbon::localeHasDiffTwoDayWords(''zh_TW'')); // bool(false) // Support short units (1y = 1 year, 1mo = 1 month, etc.) var_dump(Carbon::localeHasShortUnits(''en'')); // bool(true) var_dump(Carbon::localeHasShortUnits(''zh_TW'')); // bool(false) // Support period syntax (X times, every X, from X, to X) var_dump(Carbon::localeHasPeriodSyntax(''en'')); // bool(true) var_dump(Carbon::localeHasPeriodSyntax(''zh_TW'')); // bool(false) 

因此，这是处理Carbon国际化的新推荐方法。

$date = Carbon::now()->locale(''fr_FR'');

echo $date->locale();            // fr_FR echo "\n"; echo $date->diffForHumans(); // il y a 1 seconde echo "\n"; echo $date->monthName; // février echo "\n"; echo $date->isoFormat(''LLLL''); // vendredi 14 février 2020 16:05 

该->locale()方法仅更改当前实例的语言，并且优先于全局设置。我们建议您使用这种方法，以免与其他可能使用Carbon的地方或第三方库发生冲突。但是，为了避免->locale() 每次都调用，可以使用工厂。

// Let say Martin from Paris and John from Chicago play chess
$martinDateFactory = new Factory([
    ''locale'' => ''fr_FR'', ''timezone'' => ''Europe/Paris'', ]); $johnDateFactory = new Factory([ ''locale'' => ''en_US'', ''timezone'' => ''America/Chicago'', ]); // Each one will see date in his own language and timezone // When Martin moves, we display things in French, but we notify John in English: $gameStart = Carbon::parse(''2018-06-15 12:34:00'', ''UTC''); $move = Carbon::now(''UTC''); $toDisplay = $martinDateFactory->make($gameStart)->isoFormat(''lll'')."\n". $martinDateFactory->make($move)->calendar()."\n"; $notificationForJohn = $johnDateFactory->make($gameStart)->isoFormat(''lll'')."\n". $johnDateFactory->make($move)->calendar()."\n"; echo $toDisplay; /* 15 juin 2018 12:34 Aujourd’hui à 16:05 */ echo $notificationForJohn; /* Jun 15, 2018 12:34 PM Today at 4:05 PM */ 

您可以在工厂上调用任何静态Carbon方法（进行制造，现在，昨天，明天，解析，创建等）。工厂（以及生成CarbonImmutable实例的FactoryImmutable）是使事物保持组织和隔离的最佳方法。我们建议您尽可能多地使用UTC日期，然后在向用户显示日期之前在本地（或在工厂使用）时区和语言。

工厂实际要做的是使用方法名称作为静态构造函数，然后使用调用settings() 方法，这是一种将区域设置，时区，月/年溢出等呼叫设置分组的方法。（有关完整列表，请参见参考资料。）

$factory = new Factory([
    ''locale'' => ''fr_FR'',
    ''timezone'' => ''Europe/Paris'', ]); $factory->now(); // You can recall $factory as needed to generate new instances with same settings // is equivalent to: Carbon::now()->settings([ ''locale'' => ''fr_FR'', ''timezone'' => ''Europe/Paris'', ]); // Important note: timezone setting calls ->shiftTimezone() and not ->setTimezone(), // It means it does not just set the timezone, but shift the time too: echo Carbon::today()->setTimezone(''Asia/Tokyo'')->format(''d/m G\h e''); // 14/02 9h Asia/Tokyo echo "\n"; echo Carbon::today()->shiftTimezone(''Asia/Tokyo'')->format(''d/m G\h e''); // 14/02 0h Asia/Tokyo 

settings() 还允许传递本地宏：

$date = Carbon::parse(''Today 12:34:56'')->settings([
    ''macros'' => [
        ''lastSecondDigit'' => function () { return self::this()->second % 10; }, ], ]); echo $date->lastSecondDigit(); // 6 var_dump($date->hasLocalMacro(''lastSecondDigit'')); // bool(true) // You can also retrieve the macro closure using ->getLocalMacro(''lastSecondDigit'') 

之后可以使用更改工厂设置，也可以将其setSettings(array $settings)与现有设置合并，mergeSettings(array $settings)然后可以将要生成的类初始化为构造的第二个参数，然后使用进行更改 setClassName(string $className)。

$factory = new Factory([''locale'' => ''ja''], CarbonImmutable::class); var_dump($factory->now()->locale); // string(2) "ja" var_dump(get_class($factory->now())); // string(22) "Carbon\CarbonImmutable" class MyCustomCarbonSubClass extends Carbon { /* ... */ } $factory ->setSettings([''locale'' => ''zh_CN'']) ->setClassName(MyCustomCarbonSubClass::class); var_dump($factory->now()->locale); // string(5) "zh_CN" var_dump(get_class($factory->now())); // string(22) "MyCustomCarbonSubClass" 

以前是Carbon::setLocale在全球范围内设置的。但是对于其他静态设置器，我们强烈建议您不要使用它。它违反了隔离原则，因为该配置将适用于所有使用Carbon的类。

您可能也知道formatLocalized()Carbon 1中的方法。此方法在Carbon 2中仍然相同，但最好isoFormat()改用。

->isoFormat(string $format): string使用ISO格式而不是特定于PHP的格式，并使用内部翻译而不是需要在部署应用程序的每台计算机上安装的语言包。isoFormat该方法与momentjs格式方法兼容 ，这意味着您可以使用与前端或node.js相同的格式字符串。这里有些例子：

$date = Carbon::parse(''2018-06-15 17:34:15.984512'', ''UTC'');
echo $date->isoFormat(''MMMM Do YYYY, h:mm:ss a''); // June 15th 2018, 5:34:15 pm echo "\n"; echo $date->isoFormat(''dddd''); // Friday echo "\n"; echo $date->isoFormat(''MMM Do YY''); // Jun 15th 18 echo "\n"; echo $date->isoFormat(''YYYY [escaped] YYYY''); // 2018 escaped 2018 

您还可以根据ISO格式的字符串创建日期：

$date = Carbon::createFromIsoFormat(''!YYYY-MMMM-D h:mm:ss a'', ''2019-January-3 6:33:24 pm'', ''UTC'');
echo $date->isoFormat(''M/D/YY HH:mm''); // 1/3/19 18:33 

->isoFormat 对日期名称和月份名称使用上下文化的方法，因为它们在某些语言中可以具有多种形式，请参见以下示例：

$date = Carbon::parse(''2018-03-16'')->locale(''uk'');
echo $date->getTranslatedDayName(''[в] dddd''); // п’ятницю // By providing a context, we''re saying translate day name like in a format such as [в] dddd // So the context itself has to be translated first consistently. echo "\n"; echo $date->getTranslatedDayName(''[наступної] dddd''); // п’ятниці echo "\n"; echo $date->getTranslatedDayName(''dddd, MMM''); // п’ятниця echo "\n"; // The same goes for short/minified variants: echo $date->getTranslatedShortDayName(''[наступної] dd''); // пт echo "\n"; echo $date->getTranslatedMinDayName(''[наступної] ddd''); // пт echo "\n"; // And the same goes for months $date->locale(''ru''); echo $date->getTranslatedMonthName(''Do MMMM''); // марта echo "\n"; echo $date->getTranslatedMonthName(''MMMM YYYY''); // март echo "\n"; // Short variant echo $date->getTranslatedShortMonthName(''Do MMM''); // мар echo "\n"; echo $date->getTranslatedShortMonthName(''MMM YYYY''); // мар echo "\n"; // And so you can force a different context to get those variants: echo $date->isoFormat(''Do MMMM''); // 16-го марта echo "\n"; echo $date->isoFormat(''MMMM YYYY''); // март 2018 echo "\n"; echo $date->isoFormat(''Do MMMM'', ''MMMM YYYY''); // 16-го март echo "\n"; echo $date->isoFormat(''MMMM YYYY'', ''Do MMMM''); // марта 2018 echo "\n"; 

这是可用替代品的完整列表（示例带有 $date = Carbon::parse(''2017-01-05 17:04:05.084512'');）：

也可以使用一些宏格式。以下是每种语言的示例：

与宏格式一起使用时createFromIsoFormat，可以指定区域设置以选择应以哪种语言搜索宏格式。

$date = Carbon::createFromIsoFormat(''LLLL'', ''Monday 11 March 2019 16:28'', null, ''fr''); echo $date->isoFormat(''M/D/YY HH:mm''); // 3/11/19 16:28 

另一种有用的翻译方法是calendar($referenceTime = null, array $formats = []): string：

$date = CarbonImmutable::now();
echo $date->calendar();                                      // Today at 4:05 PM
echo "\n"; echo $date->sub(''1 day 3 hours'')->calendar(); // Yesterday at 1:05 PM echo "\n"; echo $date->sub(''3 days 10 hours 23 minutes'')->calendar(); // Last Tuesday at 5:42 AM echo "\n"; echo $date->sub(''8 days'')->calendar(); // 02/06/2020 echo "\n"; echo $date->add(''1 day 3 hours'')->calendar(); // Tomorrow at 7:05 PM echo "\n"; echo $date->add(''3 days 10 hours 23 minutes'')->calendar(); // Tuesday at 2:28 AM echo "\n"; echo $date->add(''8 days'')->calendar(); // 02/22/2020 echo "\n"; echo $date->locale(''fr'')->calendar(); // Aujourd’hui à 16:05 

如果您知道momentjs，那么它的工作方式相同。您可以将参考日期作为第二个参数传递，否则现在使用。您可以使用第二个参数来自定义一种或多种格式（作为数组键传递的格式为：sameDay，nextDay，nextWeek，lastDay，lastWeek和sameElse）：

$date1 = CarbonImmutable::parse(''2018-01-01 12:00:00'');
$date2 = CarbonImmutable::parse(''2018-01-02 8:00:00'');

echo $date1->calendar($date2, [ ''lastDay'' => ''[Previous day at] LT'', ]); // Previous day at 12:00 PM 

单击此处是上一个Carbon版本支持的279个语言环境（和822个区域变体）的概述：

如果您可以添加缺少的翻译或缺少的语言，请转到翻译工具，欢迎您的帮助。

请注意，如果您使用Laravel 5.5+，将根据当前的上次App:setLocale执行自动设置语言环境 。因此diffForHumans，isoFormat，translatedFormat和本地化如属性->dayName或->monthName将被透明地本地化。

默认情况下，每个Carbon，CarbonImmutable，CarbonInterval或CarbonPeriod实例都Carbon\Translator根据其区域设置链接到一个 实例。您可以使用getLocalTranslator()/ 获取和/或更改它setLocalTranslator(Translator $translator)。

如果您更喜欢date()pattern，则可以translatedFormat()像使用模式一样使用，format() 但是使用当前语言环境来翻译字符串。

$date = Carbon::parse(''2018-03-16 15:45'')->locale(''uk'');

echo $date->translatedFormat(''g:i a l jS F Y''); // 3:45 дня п’ятниця 16-го березня 2018 

请注意，W不支持某些字母之类的字母，因为它们不能安全翻译，并且 translatedFormat语法比短，但可能性比少isoFormat()。

您可以自定义format()方法的行为，以使用任何其他方法或自定义方法来代替PHP DateTime类中的本机方法：

$date = Carbon::parse(''2018-03-16 15:45'')->locale(''ja'');

echo $date->format(''g:i a l jS F Y''); // 3:45 pm Friday 16th March 2018 echo "\n"; $date->settings([''formatFunction'' => ''translatedFormat'']); echo $date->format(''g:i a l jS F Y''); // 3:45 午後 金曜日 16日 3月 2018 echo "\n"; $date->settings([''formatFunction'' => ''isoFormat'']); echo $date->format(''LL''); // 2018年3月16日 echo "\n"; // When you set a custom format() method you still can access the native method using rawFormat() echo $date->rawFormat(''D''); // Fri 

您可以使用Carbon中可用的日期翻译将字符串从一种语言翻译为另一种：

echo Carbon::translateTimeString(''mercredi 8 juillet'', ''fr'', ''nl'');
// woensdag 8 juli echo "\n"; // You can select translations to use among available constants: // - CarbonInterface::TRANSLATE_MONTHS // - CarbonInterface::TRANSLATE_DAYS // - CarbonInterface::TRANSLATE_UNITS // - CarbonInterface::TRANSLATE_MERIDIEM // - CarbonInterface::TRANSLATE_ALL (all above) // You can combine them with pipes: like below (translate units and days but not months and meridiem): echo Carbon::translateTimeString(''mercredi 8 juillet + 3 jours'', ''fr'', ''nl'', CarbonInterface::TRANSLATE_DAYS | CarbonInterface::TRANSLATE_UNITS); // woensdag 8 juillet + 3 dagen 

如果未指定输入语言环境，Carbon::getLocale()则改为使用。如果未指定输出语言环境，"en"则改为使用。您还可以使用实例的语言环境进行翻译：

echo Carbon::now()->locale(''fr'')->translateTimeStringTo(''mercredi 8 juillet + 3 jours'', ''nl'');
// woensdag 8 juli + 3 dagen 

您可以使用任何语言的字符串直接使用创建日期对象parseFromLocale：

$date = Carbon::parseFromLocale(''mercredi 6 mars 2019 + 3 jours'', ''fr'', ''UTC''); // timezone is optional echo $date->isoFormat(''LLLL''); // Saturday, March 9, 2019 12:00 AM 

或使用自定义格式createFromLocaleFormat （使用date()模式进行替换）：

$date = Carbon::createFromLocaleFormat(''!d/F/y'', ''fr'', ''25/Août/19'', ''Europe/Paris''); // timezone is optional echo $date->isoFormat(''LLLL''); // Sunday, August 25, 2019 12:00 AM 

使用ISO格式的等效方法是createFromLocaleIsoFormat：

$date = Carbon::createFromLocaleIsoFormat(''!DD/MMMM/YY'', ''fr'', ''25/Août/19'', ''Europe/Paris''); // timezone is optional echo $date->isoFormat(''LLLL''); // Sunday, August 25, 2019 12:00 AM 

要获取有关语言的一些有趣信息（例如完整的ISO名称或本机名称，地区（例如，显示在语言选择器中）），可以使用getAvailableLocalesInfo。

$zhTwInfo = Carbon::getAvailableLocalesInfo()[''zh_TW''];
$srCyrlInfo = Carbon::getAvailableLocalesInfo()[''sr_Cyrl''];
$caInfo = Carbon::getAvailableLocalesInfo()[''ca'']; var_dump($zhTwInfo->getId()); // string(5) "zh_TW" var_dump($zhTwInfo->getNames()); /* array(2) { ["isoName"]=> string(7) "Chinese" ["nativeName"]=> string(38) "中文 (Zhōngwén), 汉语, 漢語" } */ var_dump($zhTwInfo->getCode()); // string(2) "zh" var_dump($zhTwInfo->getVariant()); // NULL var_dump($srCyrlInfo->getVariant()); // string(4) "Cyrl" var_dump($zhTwInfo->getVariantName()); // NULL var_dump($srCyrlInfo->getVariantName()); // string(8) "Cyrillic" var_dump($zhTwInfo->getRegion()); // string(2) "TW" var_dump($srCyrlInfo->getRegion()); // NULL var_dump($zhTwInfo->getRegionName()); // string(25) "Taiwan, Province of China" var_dump($srCyrlInfo->getRegionName()); // NULL var_dump($zhTwInfo->getFullIsoName()); // string(7) "Chinese" var_dump($caInfo->getFullIsoName()); // string(18) "Catalan, Valencian" var_dump($zhTwInfo->getFullNativeName()); // string(38) "中文 (Zhōngwén), 汉语, 漢語" var_dump($caInfo->getFullNativeName()); // string(18) "català, valencià" var_dump($zhTwInfo->getIsoName()); // string(7) "Chinese" var_dump($caInfo->getIsoName()); // string(7) "Catalan" var_dump($zhTwInfo->getNativeName()); // string(20) "中文 (Zhōngwén)" var_dump($caInfo->getNativeName()); // string(7) "català" var_dump($zhTwInfo->getIsoDescription()); // string(35) "Chinese (Taiwan, Province of China)" var_dump($srCyrlInfo->getIsoDescription()); // string(18) "Serbian (Cyrillic)" var_dump($caInfo->getIsoDescription()); // string(7) "Catalan" var_dump($zhTwInfo->getNativeDescription()); // string(48) "中文 (Zhōngwén) (Taiwan, Province of China)" var_dump($srCyrlInfo->getNativeDescription()); // string(34) "српски језик (Cyrillic)" var_dump($caInfo->getNativeDescription()); // string(7) "català" var_dump($zhTwInfo->getFullIsoDescription()); // string(35) "Chinese (Taiwan, Province of China)" var_dump($srCyrlInfo->getFullIsoDescription()); // string(18) "Serbian (Cyrillic)" var_dump($caInfo->getFullIsoDescription()); // string(18) "Catalan, Valencian" var_dump($zhTwInfo->getFullNativeDescription()); // string(66) "中文 (Zhōngwén), 汉语, 漢語 (Taiwan, Province of China)" var_dump($srCyrlInfo->getFullNativeDescription()); // string(34) "српски језик (Cyrillic)" var_dump($caInfo->getFullNativeDescription()); // string(18) "català, valencià" $srCyrlInfo->setIsoName(''foo, bar'')->setNativeName(''biz, baz''); var_dump($srCyrlInfo->getIsoName()); // string(3) "foo" var_dump($srCyrlInfo->getFullIsoName()); // string(8) "foo, bar" var_dump($srCyrlInfo->getFullIsoDescription()); // string(19) "foo, bar (Cyrillic)" var_dump($srCyrlInfo->getNativeName()); // string(3) "biz" var_dump($srCyrlInfo->getFullNativeName()); // string(8) "biz, baz" var_dump($srCyrlInfo->getFullNativeDescription()); // string(19) "biz, baz (Cyrillic)" // You can also access directly regions/languages lists: var_dump(\Carbon\Language::all()[''zh'']); /* array(2) { ["isoName"]=> string(7) "Chinese" ["nativeName"]=> string(38) "中文 (Zhōngwén), 汉语, 漢語" } */ var_dump(\Carbon\Language::regions()[''TW'']); /* string(25) "Taiwan, Province of China" */ 

请让我感谢一些项目，这些项目对我们支持更多区域设置和国际化功能很有帮助：

• jenssegers / date：此项目中的许多功能在扩展Carbon本身之前都对Carbon进行了扩展。
• momentjs：许多功能均受momentjs的启发，并与该前端对项目兼容。
• glibc是添加和检查语言的强大基础。
• svenfuchs / rails-i18n还帮助添加和检查语言。
• 我们经常使用glosbe.com来检查翻译和填空。

测试辅助

测试方法允许您设置创建“ now”实例时要返回的Carbon实例（真实或模拟）。从Carbon检索任何相对时间（现在，今天，昨天，下个月等）时，将使用提供的实例。

$knownDate = Carbon::create(2001, 5, 21, 12); // create testing date Carbon::setTestNow($knownDate); // set the mock (of course this could be a real mock object) echo Carbon::getTestNow(); // 2001-05-21 12:00:00 echo Carbon::now(); // 2001-05-21 12:00:00 echo new Carbon(); // 2001-05-21 12:00:00 echo Carbon::parse(); // 2001-05-21 12:00:00 echo new Carbon(''now''); // 2001-05-21 12:00:00 echo Carbon::parse(''now''); // 2001-05-21 12:00:00 echo Carbon::create(2001, 4, 21, 12)->diffForHumans(); // 1 month ago var_dump(Carbon::hasTestNow()); // bool(true) Carbon::setTestNow(); // clear the mock var_dump(Carbon::hasTestNow()); // bool(false) echo Carbon::now(); // 2020-02-14 16:05:24 

一个更有意义的完整示例：

class SeasonalProduct
{
    protected $price; public function __construct($price) { $this->price = $price; } public function getPrice() { $multiplier = 1; if (Carbon::now()->month == 12) { $multiplier = 2; } return $this->price * $multiplier; } } $product = new SeasonalProduct(100); Carbon::setTestNow(Carbon::parse(''first day of March 2000'')); echo $product->getPrice(); // 100 Carbon::setTestNow(Carbon::parse(''first day of December 2000'')); echo $product->getPrice(); // 200 Carbon::setTestNow(Carbon::parse(''first day of May 2000'')); echo $product->getPrice(); // 100 Carbon::setTestNow(); 

相对短语也会根据给定的“ now”实例进行模拟。

$knownDate = Carbon::create(2001, 5, 21, 12); // create testing date Carbon::setTestNow($knownDate); // set the mock echo new Carbon(''tomorrow''); // 2001-05-22 00:00:00 ... notice the time ! echo new Carbon(''yesterday''); // 2001-05-20 00:00:00 echo new Carbon(''next wednesday''); // 2001-05-23 00:00:00 echo new Carbon(''last friday''); // 2001-05-18 00:00:00 echo new Carbon(''this thursday''); // 2001-05-24 00:00:00 Carbon::setTestNow(); // always clear it ! 

被视为相对修饰语的单词列表为：

• +
• --
• 前
• 第一
• 下一个
• 持续
• 这个
• 今天
• 明天
• 昨天

请注意，类似于next（），previous（）和Modify（）方法，其中一些相对修饰符会将时间设置为00:00:00。

Carbon::parse($time, $tz)并且new Carbon($time, $tz)既可以采取时区作为第二个参数。

echo Carbon::parse(''2012-9-5 23:26:11.223'', ''Europe/Paris'')->timezone->getName(); // Europe/Paris

有关更高级的碳测试功能，请参见Carbonite。

Carbonite是一个附加软件包，您可以使用composer轻松安装：composer require --dev kylekatarnls/carbonite 然后像讲故事一样在单元测试中花费时间：

use Carbon\Carbonite;在文件顶部添加导入。

$holidays = CarbonPeriod::create(''2019-12-23'', ''2020-01-06'', CarbonPeriod::EXCLUDE_END_DATE);

Carbonite::freeze(''2019-12-22''); // Freeze the time to a given date var_dump($holidays->isStarted()); // bool(false) // Then go to anytime: Carbonite::elapse(''1 day''); var_dump($holidays->isInProgress()); // bool(true) Carbonite::jumpTo(''2020-01-05 22:00''); var_dump($holidays->isEnded()); // bool(false) Carbonite::elapse(''2 hours''); var_dump($holidays->isEnded()); // bool(true) Carbonite::rewind(''1 microsecond''); var_dump($holidays->isEnded()); // bool(false) Carbonite::release(); // Release time after each test 

吸气剂

吸气剂是通过PHP的__get()方法实现的。这样一来，您就可以像对待属性而不是调用函数一样访问该值。

$dt = Carbon::parse(''2012-10-5 23:26:11.123789'');

// These getters specifically return integers, ie intval()
var_dump($dt->year);                                         // int(2012) var_dump($dt->month); // int(10) var_dump($dt->day); // int(5) var_dump($dt->hour); // int(23) var_dump($dt->minute); // int(26) var_dump($dt->second);

// string(9) "centuries" var_dump(Carbon::pluralUnit(''millennium'')); // string(9) "millennia" 

二传手

以下设置器是通过PHP的__set()方法实现的。在此需要注意的是，除了显式设置时区的明显例外之外，所有设置器都不会更改实例的时区。具体来说，设置时间戳不会将相应时区设置为UTC。

$dt = Carbon::now();

$dt->year = 1975;
$dt->month = 13; // would force year++ and month = 1 $dt->month = 5; $dt->day = 21; $dt->hour = 22; $dt->minute = 32; $dt->second = 5; $dt->timestamp = 169957925; // This will not change the timezone // Same as: $dt->setTimestamp(169957925); $dt->timestamp(169957925); // Set the timezone via DateTimeZone instance or string $dt->tz = new DateTimeZone(''Europe/London''); $dt->tz = ''Europe/London''; // The ->timezone is also available for backward compatibility but // it will be overridden by native php DateTime class as soon as // the object is dump (passed foreach, serialize, var_export, clone, etc.) // making the Carbon setter inefficient, if it happen, you can cleanup // those overridden properties by calling ->cleanupDumpProperties() on // the instance, but we rather recommend to simply use ->tz instead // of ->timezone everywhere. // verbose way: $dt->setYear(2001); echo $dt->year; // 2001 echo "\n"; // set/get method: $dt->year(2002); echo $dt->year(); // 0000-05-22 03:32:05 echo "\n"; // dynamic way: $dt->set(''year'', 2003); echo $dt->get(''year''); // 2003 echo "\n"; // these methods exist for every units even for calculated properties such as: echo $dt->dayOfYear(35)->format(''Y-m-d''); // 2003-02-04 

周数

如果您熟悉momentjs，那么您会发现所有Week方法都工作相同。它们大多数具有iso {Method}变体。Week方法遵循当前语言环境的规则（例如，使用en_US，默认语言环境，一周的第一天为Sunday，一年的第一周为包含1月1日的一周）。ISO方法遵循ISO 8601规范，这意味着星期从星期一开始，一年的第一周是包含1月4日的星期。

$en = CarbonImmutable::now()->locale(''en_US'');
$ar = CarbonImmutable::now()->locale(''ar'');

var_dump($en->firstWeekDay); // int(0) var_dump($en->lastWeekDay); // int(6) var_dump($en->startOfWeek()->format(''Y-m-d H:i'')); // string(16) "2020-02-09 00:00" var_dump($en->endOfWeek()->format(''Y-m-d H:i'')); // string(16) "2020-02-15 23:59" echo "-----------\n"; // We still can force to use an other day as start/end of week $start = $en->startOfWeek(Carbon::TUESDAY); $end = $en->endOfWeek(Carbon::MONDAY); var_dump($start->format(''Y-m-d H:i'')); // string(16) "2020-02-11 00:00" var_dump($end->format(''Y-m-d H:i'')); // string(16) "2020-02-17 23:59" echo "-----------\n"; var_dump($ar->firstWeekDay); // int(6) var_dump($ar->lastWeekDay); // int(5) var_dump($ar->startOfWeek()->format(''Y-m-d H:i'')); // string(16) "2020-02-08 00:00" var_dump($ar->endOfWeek()->format(''Y-m-d H:i'')); // string(16) "2020-02-14 23:59" $en = CarbonImmutable::parse(''2015-02-05''); // use en_US as default locale echo "-----------\n"; var_dump($en->weeksInYear()); // int(52) var_dump($en->isoWeeksInYear()); // int(53) $en = CarbonImmutable::parse(''2017-02-05''); echo "-----------\n"; var_dump($en->week()); // int(6) var_dump($en->isoWeek()); // int(5) var_dump($en->week(1)->format(''Y-m-d H:i'')); // string(16) "2017-01-01 00:00" var_dump($en->isoWeek(1)->format(''Y-m-d H:i'')); // string(16) "2017-01-08 00:00" var_dump($en->weekday()); // int(0) var_dump($en->isoWeekday()); // int(7) var_dump($en->weekday(3)->format(''Y-m-d H:i'')); // string(16) "2017-02-08 00:00" var_dump($en->isoWeekday(3)->format(''Y-m-d H:i'')); // string(16) "2017-02-01 00:00" $en = CarbonImmutable::parse(''2017-01-01''); echo "-----------\n"; var_dump($en->weekYear()); // int(2017) var_dump($en->isoWeekYear()); // int(2016) var_dump($en->weekYear(2016)->format(''Y-m-d H:i'')); // string(16) "2015-12-27 00:00" var_dump($en->isoWeekYear(2016)->format(''Y-m-d H:i'')); // string(16) "2017-01-01 00:00" var_dump($en->weekYear(2015)->format(''Y-m-d H:i'')); // string(16) "2014-12-28 00:00" var_dump($en->isoWeekYear(2015)->format(''Y-m-d H:i'')); // string(16) "2015-12-27 00:00" // Note you still can force first day of week and year to use: $en = CarbonImmutable::parse(''2017-01-01''); echo "-----------\n"; var_dump($en->weeksInYear(null, 6, 12)); // int(52) var_dump($en->isoWeeksInYear(null, 6, 12)); // int(52) var_dump($en->week(null, 6, 12)); // int(52) var_dump($en->isoWeek(null, 6, 12)); // int(52) var_dump($en->weekYear(null, 6, 12)); // int(2016) var_dump($en->isoWeekYear(null, 6, 12)); // int(2016) var_dump($en->weekYear(2016, 6, 12)->format(''Y-m-d H:i'')); // string(16) "2017-01-01 00:00" var_dump($en->isoWeekYear(2016, 6, 12)->format(''Y-m-d H:i'')); // string(16) "2017-01-01 00:00" // Then you can see using a method or its ISO variant return identical results 

流利的二传手

您可以将任何基本单元称为设置器或某些分组的设置器：

$dt = Carbon::now();

$dt->year(1975)->month(5)->day(21)->hour(22)->minute(32)->second(5)->toDateTimeString(); $dt->setDate(1975, 5, 21)->setTime(22, 32, 5)->toDateTimeString(); $dt->setDate(1975, 5, 21)->setTimeFromTimeString(''22:32:05'')->toDateTimeString(); $dt->setDateTime(1975, 5, 21, 22, 32, 5)->toDateTimeString(); // All allow microsecond as optional argument $dt->year(1975)->month(5)->day(21)->hour(22)->minute(32)->second(5)->microsecond(123456)->toDateTimeString(); $dt->setDate(1975, 5, 21)->setTime(22, 32, 5, 123456)->toDateTimeString(); $dt->setDate(1975, 5, 21)->setTimeFromTimeString(''22:32:05.123456'')->toDateTimeString(); $dt->setDateTime(1975, 5, 21, 22, 32, 5, 123456)->toDateTimeString(); $dt->timestamp(169957925); // Note: timestamps are UTC but do not change the date timezone $dt->timezone(''Europe/London'')->tz(''America/Toronto'')->setTimezone(''America/Vancouver''); 

您还可以与其他DateTime / Carbon对象分别设置日期和时间：

$source1 = new Carbon(''2010-05-16 22:40:10.1'');

$dt = new Carbon(''2001-01-01 01:01:01.2''); $dt->setTimeFrom($source1); echo $dt; // 2001-01-01 22:40:10 $source2 = new DateTime(''2013-09-01 09:22:56.2''); $dt->setDateFrom($source2); echo $dt; // 2013-09-01 22:40:10 $dt->setDateTimeFrom($source2); // set date and time including microseconds // bot not settings as locale, timezone, options. 

IsSet

PHP函数__isset()已实现。这样做是因为某些外部系统（例如Twig）在使用属性之前先对其进行了验证。这是使用isset()or empty() 方法完成的。你可以阅读更多有关这些的PHP站点：__isset（） ，isset（）函数，空（） 。

var_dump(isset(Carbon::now()->iDoNotExist));       // bool(false)
var_dump(isset(Carbon::now()->hour));              // bool(true)
var_dump(empty(Carbon::now()->iDoNotExist)); // bool(true) var_dump(empty(Carbon::now()->year)); // bool(false) 

字符串格式

所有可用toXXXString()方法都依赖于基类方法DateTime :: format（）。您会注意到__toString() 定义了该方法，该方法允许在字符串上下文中使用Carbon实例时，将其打印为漂亮的日期时间字符串。

$dt = Carbon::create(1975, 12, 25, 14, 15, 16); var_dump($dt->toDateTimeString() == $dt); // bool(true) => uses __toString() echo $dt->toDateString(); // 1975-12-25 echo $dt->toFormattedDateString(); // Dec 25, 1975 echo $dt->toTimeString(); // 14:15:16 echo $dt->toDateTimeString(); // 1975-12-25 14:15:16 echo $dt->toDayDateTimeString(); // Thu, Dec 25, 1975 2:15 PM // ... of course format() is still available echo $dt->format(''l jS \\of F Y h:i:s A''); // Thursday 25th of December 1975 02:15:16 PM // The reverse hasFormat method allows you to test if a string looks like a given format var_dump($dt->hasFormat(''Thursday 25th December 1975 02:15:16 PM'', ''l jS F Y h:i:s A'')); // bool(true) 

您还可以设置在发生类型变戏法时Y-m-d H:i:s使用的默认__toString（）格式（默认为）。

echo $dt;                                          // 1975-12-25 14:15:16
echo "\n"; $dt->settings([ ''toStringFormat'' => ''jS \o\f F, Y g:i:s a'', ]); echo $dt; // 25th of December, 1975 2:15:16 pm // As any setting, you can get the current value for a given date using: var_dump($dt->getSettings()); /* array(3) { ["toStringFormat"]=> string(20) "jS \o\f F, Y g:i:s a" ["locale"]=> string(2) "en" ["timezone"]=> string(3) "UTC" }*/ 

作为设置的一部分，''toStringFormat''也可以在工厂中使用。它也可能是一个闭包，因此您可以在字符串强制转换上运行任何代码。

如果您使用Carbon 1或要将其作为默认格式全局应用，则可以使用：

$dt = Carbon::create(1975, 12, 25, 14, 15, 16); Carbon::setToStringFormat(''jS \o\f F, Y g:i:s a''); echo $dt; // 25th of December, 1975 2:15:16 pm echo "\n"; Carbon::resetToStringFormat(); echo $dt; // 1975-12-25 14:15:16 

注意：有关本地化支持，请参见“ 本地化”部分。

常用格式

以下是DateTime类提供的常见格式的包装。

您可以使用该方法 根据给定的源实例（根据需要用作参考）carbonize将许多事物转换为Carbon实例。它返回一个新实例。

比较方式

通过以下功能可以进行简单比较。请记住，比较是在UTC时区进行的，因此情况并非总是如此。

echo Carbon::now()->tzName;                        // UTC
$first = Carbon::create(2012, 9, 5, 23, 26, 11); $second = Carbon::create(2012, 9, 5, 20, 26, 11, ''America/Vancouver''); echo $first->toDateTimeString(); // 2012-09-05 23:26:11 echo $first->tzName; // UTC echo $second->toDateTimeString(); // 2012-09-05 20:26:11 echo $second->tzName; // America/Vancouver var_dump($first->equalTo($second)); // bool(false) // equalTo is also available on CarbonInterval and CarbonPeriod var_dump($first->notEqualTo($second)); // bool(true) // notEqualTo is also available on CarbonInterval and CarbonPeriod var_dump($first->greaterThan($second)); // bool(false) // greaterThan is also available on CarbonInterval var_dump($first->greaterThanOrEqualTo($second)); // bool(false) // greaterThanOrEqualTo is also available on CarbonInterval var_dump($first->lessThan($second)); // bool(true) // lessThan is also available on CarbonInterval var_dump($first->lessThanOrEqualTo($second)); // bool(true) // lessThanOrEqualTo is also available on CarbonInterval $first->setDateTime(2012, 1, 1, 0, 0, 0); $second->setDateTime(2012, 1, 1, 0, 0, 0); // Remember tz is ''America/Vancouver'' var_dump($first->equalTo($second)); // bool(false) var_dump($first->notEqualTo($second)); // bool(true) var_dump($first->greaterThan($second)); // bool(false) var_dump($first->greaterThanOrEqualTo($second)); // bool(false) var_dump($first->lessThan($second)); // bool(true) var_dump($first->lessThanOrEqualTo($second)); // bool(true) // All have short hand aliases and PHP equivalent code: var_dump($first->eq($second)); // bool(false) var_dump($first->equalTo($second)); // bool(false) var_dump($first == $second); // bool(false) var_dump($first->ne($second)); // bool(true) var_dump($first->notEqualTo($second)); // bool(true) var_dump($first != $second); // bool(true) var_dump($first->gt($second)); // bool(false) var_dump($first->greaterThan($second)); // bool(false) var_dump($first->isAfter($second)); // bool(false) var_dump($first > $second); // bool(false) var_dump($first->gte($second)); // bool(false) var_dump($first->greaterThanOrEqualTo($second)); // bool(false) var_dump($first >= $second); // bool(false) var_dump($first->lt($second)); // bool(true) var_dump($first->lessThan($second)); // bool(true) var_dump($first->isBefore($second)); // bool(true) var_dump($first < $second); // bool(true) var_dump($first->lte($second)); // bool(true) var_dump($first->lessThanOrEqualTo($second)); // bool(true) var_dump($first <= $second); // bool(true) 

这些方法使用PHP提供的自然比较，$date1 == $date2因此所有这些方法都将在PHP 7.1之前忽略毫秒/微秒，然后从7.1开始考虑它们。

要确定当前实例是否在其他两个实例之间，可以使用适当命名的 between()方法（或isBetween()别名）。第三个参数指示是否应该进行等于比较。默认值是true，它确定其介于边界之间还是等于边界。

$first = Carbon::create(2012, 9, 5, 1); $second = Carbon::create(2012, 9, 5, 5); var_dump(Carbon::create(2012, 9, 5, 3)->between($first, $second)); // bool(true) var_dump(Carbon::create(2012, 9, 5, 5)->between($first, $second)); // bool(true) var_dump(Carbon::create(2012, 9, 5, 5)->between($first, $second, false)); // bool(false) var_dump(Carbon::create(2012, 9, 5, 5)->isBetween($first, $second, false)); // bool(false) // Rather than passing false as a third argument, you can use betweenExcluded var_dump(Carbon::create(2012, 9, 5, 5)->betweenExcluded($first, $second)); // bool(false) // All those methods are also available on CarbonInterval 

哇！您忘记了min（）和max（）吗？不。适当命名的min()和 max()方法或minimum()和maximum()别名也涵盖了这一点。与往常一样，如果指定了null，则默认参数现在为。

$dt1 = Carbon::createMidnightDate(2012, 1, 1);
$dt2 = Carbon::createMidnightDate(2014, 1, 30); echo $dt1->min($dt2); // 2012-01-01 00:00:00 echo $dt1->minimum($dt2); // 2012-01-01 00:00:00 // Also works with string echo $dt1->minimum(''2014-01-30''); // 2012-01-01 00:00:00 $dt1 = Carbon::createMidnightDate(2012, 1, 1); $dt2 = Carbon::createMidnightDate(2014, 1, 30); echo $dt1->max($dt2); // 2014-01-30 00:00:00 echo $dt1->maximum($dt2); // 2014-01-30 00:00:00 // now is the default param $dt1 = Carbon::createMidnightDate(2000, 1, 1); echo $dt1->max(); // 2020-02-14 16:05:24 echo $dt1->maximum(); // 2020-02-14 16:05:24 // Remember min and max PHP native function work fine with dates too: echo max(Carbon::create(''2002-03-15''), Carbon::create(''2003-01-07''), Carbon::create(''2002-08-25'')); // 2003-01-07 00:00:00 echo min(Carbon::create(''2002-03-15''), Carbon::create(''2003-01-07''), Carbon::create(''2002-08-25'')); // 2002-03-15 00:00:00 // This way you can pass as many dates as you want and get no ambiguities about parameters order $dt1 = Carbon::createMidnightDate(2010, 4, 1); $dt2 = Carbon::createMidnightDate(2010, 3, 28); $dt3 = Carbon::createMidnightDate(2010, 4, 16); // returns the closest of two date (no matter before or after) echo $dt1->closest($dt2, $dt3); // 2010-03-28 00:00:00 echo $dt2->closest($dt1, $dt3); // 2010-04-01 00:00:00 echo $dt3->closest($dt2, $dt1); // 2010-04-01 00:00:00 // returns the farthest of two date (no matter before or after) echo $dt1->farthest($dt2, $dt3); // 2010-04-16 00:00:00 echo $dt2->farthest($dt1, $dt3); // 2010-04-16 00:00:00 echo $dt3->farthest($dt2, $dt1); // 2010-03-28 00:00:00 

为了处理最常用的情况，有一些简单的辅助函数，希望它们的名称是显而易见的。对于now()以某种方式与（例如isToday（））进行比较的方法，now()会在与实例相同的时区中创建。

$dt = Carbon::now();
$dt2 = Carbon::createFromDate(1987, 4, 23); $dt->isSameAs(''w'', $dt2); // w is the date of the week, so this will return true if $dt and $dt2 // the same day of week (both monday or both sunday, etc.) // you can use any format and combine as much as you want. $dt->isFuture(); $dt->isPast(); $dt->isSameYear($dt2); $dt->isCurrentYear(); $dt->isNextYear(); $dt->isLastYear(); $dt->isLongYear(); // see https://en.wikipedia.org/wiki/ISO_8601#Week_dates $dt->isLeapYear(); $dt->isSameQuarter($dt2); // same quarter of the same year of the given date $dt->isSameQuarter($dt2, false); // same quarter (3 months) no matter the year of the given date $dt->isCurrentQuarter(); $dt->isNextQuarter(); // date is in the next quarter $dt->isLastQuarter(); // in previous quarter $dt->isSameMonth($dt2); // same month of the same year of the given date $dt->isSameMonth($dt2, false); // same month no matter the year of the given date $dt->isCurrentMonth(); $dt->isNextMonth(); $dt->isLastMonth(); $dt->isWeekday(); $dt->isWeekend(); $dt->isMonday(); $dt->isTuesday(); $dt->isWednesday(); $dt->isThursday(); $dt->isFriday(); $dt->isSaturday(); $dt->isSunday(); $dt->isDayOfWeek(Carbon::SATURDAY); // is a saturday $dt->isLastOfMonth(); // is the last day of the month $dt->is(''Sunday''); $dt->is(''June''); $dt->is(''2019''); $dt->is(''12:23''); $dt->is(''2 June 2019''); $dt->is(''06-02''); $dt->isSameDay($dt2); // Same day of same month of same year $dt->isCurrentDay(); $dt->isYesterday(); $dt->isToday(); $dt->isTomorrow(); $dt->isNextWeek(); $dt->isLastWeek(); $dt->isSameHour($dt2); $dt->isCurrentHour(); $dt->isSameMinute($dt2); $dt->isCurrentMinute(); $dt->isSameSecond($dt2); $dt->isCurrentSecond(); $dt->isStartOfDay(); // check if hour is 00:00:00 $dt->isMidnight(); // check if hour is 00:00:00 (isStartOfDay alias) $dt->isEndOfDay(); // check if hour is 23:59:59 $dt->isMidday(); // check if hour is 12:00:00 (or other midday hour set with Carbon::setMidDayAt()) $born = Carbon::createFromDate(1987, 4, 23); $noCake = Carbon::createFromDate(2014, 9, 26); $yesCake = Carbon::createFromDate(2014, 4, 23); $overTheHill = Carbon::now()->subYears(50); var_dump($born->isBirthday($noCake)); // bool(false) var_dump($born->isBirthday($yesCake)); // bool(true) var_dump($overTheHill->isBirthday()); // bool(true) -> default compare it to today! // isCurrentX, isSameX, isNextX and isLastX are available for each unit 

加减

默认的DateTime提供了几种不同的方法来轻松地增加和减少时间。还有 modify()，add()和sub()。modify()需要一个神奇的 日期/时间格式字符串''last day of next month''，它解析并同时适用修改add()和sub()期望DateInterval的实例，这不是那么明显，（例如，new \DateInterval(''P6YT5M'')将意味着6年5分钟）。希望在几个星期没看到代码后，使用这些流利的函数会更清晰，更容易阅读。但是，我当然不会让您选择，因为基类函数仍然可用。

$dt = Carbon::create(2012, 1, 31, 0); echo $dt->toDateTimeString(); // 2012-01-31 00:00:00 echo $dt->addCenturies(5); // 2512-01-31 00:00:00 echo $dt->addCentury(); // 2612-01-31 00:00:00 echo $dt->subCentury(); // 2512-01-31 00:00:00 echo $dt->subCenturies(5); // 2012-01-31 00:00:00 echo $dt->addYears(5); // 2017-01-31 00:00:00 echo $dt->addYear(); // 2018-01-31 00:00:00 echo $dt->subYear(); // 2017-01-31 00:00:00 echo $dt->subYears(5); // 2012-01-31 00:00:00 echo $dt->addQuarters(2); // 2012-07-31 00:00:00 echo $dt->addQuarter(); // 2012-10-31 00:00:00 echo $dt->subQuarter(); // 2012-07-31 00:00:00 echo $dt->subQuarters(2); // 2012-01-31 00:00:00 echo $dt->addMonths(60); // 2017-01-31 00:00:00 echo $dt->addMonth(); // 2017-03-03 00:00:00 equivalent of $dt->month($dt->month + 1); so it wraps echo $dt->subMonth(); // 2017-02-03 00:00:00 echo $dt->subMonths(60); // 2012-02-03 00:00:00 echo $dt->addDays(29); // 2012-03-03 00:00:00 echo $dt->addDay(); // 2012-03-04 00:00:00 echo $dt->subDay(); // 2012-03-03 00:00:00 echo $dt->subDays(29); // 2012-02-03 00:00:00 echo $dt->addWeekdays(4); // 2012-02-09 00:00:00 echo $dt->addWeekday(); // 2012-02-10 00:00:00 echo $dt->subWeekday(); // 2012-02-09 00:00:00 echo $dt->subWeekdays(4); // 2012-02-03 00:00:00 echo $dt->addWeeks(3); // 2012-02-24 00:00:00 echo $dt->addWeek(); // 2012-03-02 00:00:00 echo $dt->subWeek(); // 2012-02-24 00:00:00 echo $dt->subWeeks(3); // 2012-02-03 00:00:00 echo $dt->addHours(24); // 2012-02-04 00:00:00 echo $dt->addHour(); // 2012-02-04 01:00:00 echo $dt->subHour(); // 2012-02-04 00:00:00 echo $dt->subHours(24); // 2012-02-03 00:00:00 echo $dt->addMinutes(61); // 2012-02-03 01:01:00 echo $dt->addMinute(); // 2012-02-03 01:02:00 echo $dt->subMinute(); // 2012-02-03 01:01:00 echo $dt->subMinutes(61); // 2012-02-03 00:00:00 echo $dt->addSeconds(61); // 2012-02-03 00:01:01 echo $dt->addSecond(); // 2012-02-03 00:01:02 echo $dt->subSecond(); // 2012-02-03 00:01:01 echo $dt->subSeconds(61); // 2012-02-03 00:00:00 echo $dt->addMilliseconds(61); // 2012-02-03 00:00:00 echo $dt->addMillisecond(); // 2012-02-03 00:00:00 echo $dt->subMillisecond(); // 2012-02-03 00:00:00 echo $dt->subMillisecond(61); // 2012-02-03 00:00:00 echo $dt->addMicroseconds(61); // 2012-02-03 00:00:00 echo $dt->addMicrosecond(); // 2012-02-03 00:00:00 echo $dt->subMicrosecond(); // 2012-02-03 00:00:00 echo $dt->subMicroseconds(61); // 2012-02-03 00:00:00 // and so on for any unit: millenium, century, decade, year, quarter, month, week, day, weekday, // hour, minute, second, microsecond. // Generic methods add/sub (or subtract alias) can take many different arguments: echo $dt->add(61, ''seconds''); // 2012-02-03 00:01:01 echo $dt->sub(''1 day''); // 2012-02-02 00:01:01 echo $dt->add(CarbonInterval::months(2)); // 2012-04-02 00:01:01 echo $dt->subtract(new DateInterval(''PT1H'')); // 2012-04-01 23:01:01 

为了好玩，您还可以将负值传递给addXXX()，实际上subXXX()就是这样实现的。

PS不要担心，如果您忘记和使用，addDay(5)或者subYear(3)，我有您的支持;）

默认情况下，Carbon依赖于基础父类PHP DateTime行为。结果，增加或减少月份可能会溢出，例如：

$dt = CarbonImmutable::create(2017, 1, 31, 0); echo $dt->addMonth(); // 2017-03-03 00:00:00 echo "\n"; echo $dt->subMonths(2); // 2016-12-01 00:00:00 

从Carbon 2开始，您可以为每个实例设置本地溢出行为：

$dt = CarbonImmutable::create(2017, 1, 31, 0); $dt->settings([ ''monthOverflow'' => false, ]); echo $dt->addMonth(); // 2017-02-28 00:00:00 echo "\n"; echo $dt->subMonths(2); // 2016-11-30 00:00:00 

这将应用于方法addMonth(s)，subMonth(s)，add($x, ''month'')， sub($x, ''month'')和等效季度方法。但是它不适用于间隔对象或字符串，例如add(CarbonInterval::month())或add(''1 month'')。

存在静态助手，但已弃用。如果您确定需要应用全局设置或使用Carbon的版本1，请查看“溢出静态助手”部分

你也可以使用->addMonthsNoOverflow，->subMonthsNoOverflow， ->addMonthsWithOverflow和->subMonthsWithOverflow （或奇异的方法，没有s到“月”），明确添加/带或不带溢出子月，无论现在的模式与同为任何更大的单元（季，年，十年，百年，千年）。

$dt = Carbon::createMidnightDate(2017, 1, 31)->settings([
    ''monthOverflow'' => false, ]); echo $dt->copy()->addMonthWithOverflow(); // 2017-03-03 00:00:00 // plural addMonthsWithOverflow() method is also available echo $dt->copy()->subMonthsWithOverflow(2); // 2016-12-01 00:00:00 // singular subMonthWithOverflow() method is also available echo $dt->copy()->addMonthNoOverflow(); // 2017-02-28 00:00:00 // plural addMonthsNoOverflow() method is also available echo $dt->copy()->subMonthsNoOverflow(2); // 2016-11-30 00:00:00 // singular subMonthNoOverflow() method is also available echo $dt->copy()->addMonth(); // 2017-02-28 00:00:00 echo $dt->copy()->subMonths(2); // 2016-11-30 00:00:00 $dt = Carbon::createMidnightDate(2017, 1, 31)->settings([ ''monthOverflow'' => true, ]); echo $dt->copy()->addMonthWithOverflow(); // 2017-03-03 00:00:00 echo $dt->copy()->subMonthsWithOverflow(2); // 2016-12-01 00:00:00 echo $dt->copy()->addMonthNoOverflow(); // 2017-02-28 00:00:00 echo $dt->copy()->subMonthsNoOverflow(2); // 2016-11-30 00:00:00 echo $dt->copy()->addMonth(); // 2017-03-03 00:00:00 echo $dt->copy()->subMonths(2); // 2016-12-01 00:00:00 

多年以来一直可用。

使用未知输入时，您还可以控制任何单元的溢出：

$dt = CarbonImmutable::create(2018, 8, 30, 12, 00, 00); // Add hours without overflowing day echo $dt->addUnitNoOverflow(''hour'', 7, ''day''); // 2018-08-30 19:00:00 echo "\n"; echo $dt->addUnitNoOverflow(''hour'', 14, ''day''); // 2018-08-30 23:59:59 echo "\n"; echo $dt->addUnitNoOverflow(''hour'', 48, ''day''); // 2018-08-30 23:59:59 echo "\n-------\n"; // Substract hours without overflowing day echo $dt->subUnitNoOverflow(''hour'', 7, ''day''); // 2018-08-30 05:00:00 echo "\n"; echo $dt->subUnitNoOverflow(''hour'', 14, ''day''); // 2018-08-30 00:00:00 echo "\n"; echo $dt->subUnitNoOverflow(''hour'', 48, ''day''); // 2018-08-30 00:00:00 echo "\n-------\n"; // Set hours without overflowing day echo $dt->setUnitNoOverflow(''hour'', -7, ''day''); // 2018-08-30 00:00:00 echo "\n"; echo $dt->setUnitNoOverflow(''hour'', 14, ''day''); // 2018-08-30 14:00:00 echo "\n"; echo $dt->setUnitNoOverflow(''hour'', 25, ''day''); // 2018-08-30 23:59:59 echo "\n-------\n"; // Adding hours without overflowing month echo $dt->addUnitNoOverflow(''hour'', 7, ''month''); // 2018-08-30 19:00:00 echo "\n"; echo $dt->addUnitNoOverflow(''hour'', 14, ''month''); // 2018-08-31 02:00:00 echo "\n"; echo $dt->addUnitNoOverflow(''hour'', 48, ''month''); // 2018-08-31 23:59:59 

任何可修改的单位都可以作为这些方法的参数传递：

$units = [];
foreach ([''millennium'', ''century'', ''decade'', ''year'', ''quarter'', ''month'', ''week'', ''weekday'', ''day'', ''hour'', ''minute'', ''second'', ''millisecond'', ''microsecond''] as $unit) { $units[$unit] = Carbon::isModifiableUnit($unit); } echo json_encode($units, JSON_PRETTY_PRINT); /* { "millennium": true, "century": true, "decade": true, "year": true, "quarter": true, "month": true, "week": true, "weekday": true, "day": true, "hour": true, "minute": true, "second": true, "millisecond": true, "microsecond": true } */ 

区别

随着Carbon扩展，DateTime它继承了其方法，例如以diff()第二个date对象作为参数并返回一个DateInterval实例。

我们还提供diffAsCarbonInterval()类似行为，diff()但返回一个CarbonInterval 实例。有关更多信息，请参见CarbonInterval章节。Carbon也为每个单元添加了diff方法，例如diffInYears()，diffInMonths()等等。diffAsCarbonInterval() 和diffIn*()和floatDiffIn*()方法都可以使用2个可选参数：要与之进行比较的日期（如果缺失，则改为使用它），以及一个绝对布尔值选项（true默认情况下），该布尔值选项使该方法返回绝对值，而不管哪个日期大于另一个日期。 。如果设置为false，当调用该方法的实例大于比较日期（第一个参数或现在）时，它将返回负值。注意diff()原型是不同的：其第一个参数（日期）是必需的，其第二个参数（绝对选项）默认为false。

这些函数总是返回以指定的请求时间表示的总差。这与基类diff()函数不同，在基类函数中，DateInterval实例将返回122秒的间隔，分别为2分2秒。该diffInMinutes()函数将简单地返回2而diffInSeconds()返回122。所有值都将被截断而不是四舍五入。下面的每个函数都有一个默认的第一个参数，即要比较的Carbon实例；如果要使用，则为null now()。第二个参数同样是可选的，它指示您是否希望返回值是绝对值或相对值，可能会有一个-（负）符号（如果传入的日期小于当前实例）。这将默认为true，返回绝对值。

echo Carbon::now(''America/Vancouver'')->diffInSeconds(Carbon::now(''Europe/London'')); // 0

$dtOttawa = Carbon::createMidnightDate(2000, 1, 1, ''America/Toronto''); $dtVancouver = Carbon::createMidnightDate(2000, 1, 1, ''America/Vancouver''); echo $dtOttawa->diffInHours($dtVancouver); // 3 echo $dtVancouver->diffInHours($dtOttawa); // 3 echo $dtOttawa->diffInHours($dtVancouver, false); // 3 echo $dtVancouver->diffInHours($dtOttawa, false); // -3 $dt = Carbon::createMidnightDate(2012, 1, 31); echo $dt->diffInDays($dt->copy()->addMonth()); // 31 echo $dt->diffInDays($dt->copy()->subMonth(), false); // -31 $dt = Carbon::createMidnightDate(2012, 4, 30); echo $dt->diffInDays($dt->copy()->addMonth()); // 30 echo $dt->diffInDays($dt->copy()->addWeek()); // 7 $dt = Carbon::createMidnightDate(2012, 1, 1); echo $dt->diffInMinutes($dt->copy()->addSeconds(59)); // 0 echo $dt->diffInMinutes($dt->copy()->addSeconds(60)); // 1 echo $dt->diffInMinutes($dt->copy()->addSeconds(119)); // 1 echo $dt->diffInMinutes($dt->copy()->addSeconds(120)); // 2 echo $dt->addSeconds(120)->secondsSinceMidnight(); // 120 $interval = $dt->diffAsCarbonInterval($dt->copy()->subYears(3), false); // diffAsCarbonInterval use same arguments as diff($other, $absolute) // (native method from \DateTime) // except $absolute is true by default for diffAsCarbonInterval and false for diff // $absolute parameter allow to get signed value if false, or always positive if true echo ($interval->invert ? ''minus '' : ''plus '') . $interval->years; // minus 3 

这些方法的结果被截断。这意味着diffInMinutes对于包含1和排除2之间的任何差值，将返回1。但是相同的方法可用于浮点结果：

echo Carbon::parse(''06:01:23.252987'')->floatDiffInSeconds(''06:02:34.321450'');    // 71.068463
echo Carbon::parse(''06:01:23'')->floatDiffInMinutes(''06:02:34''); // 1.1833333333333 echo Carbon::parse(''06:01:23'')->floatDiffInHours(''06:02:34''); // 0.019722222222222 // Those methods are absolute by default but can return negative value // setting the second argument to false when start date is greater than end date echo Carbon::parse(''12:01:23'')->floatDiffInHours(''06:02:34'', false); // -5.9802777777778 echo Carbon::parse(''2000-01-01 12:00'')->floatDiffInDays(''2000-02-11 06:00''); // 40.75 echo Carbon::parse(''2000-01-15 12:00'')->floatDiffInMonths(''2000-02-24 06:00''); // 1.301724137931 // floatDiffInMonths count as many full months as possible from the start date, then consider the number // of days in the months for ending chunks to reach the end date // So the following result (ending with 24 march is different from previous one with 24 february): echo Carbon::parse(''2000-02-15 12:00'')->floatDiffInMonths(''2000-03-24 06:00''); // 1.2822580645161 // floatDiffInYears apply the same logic (and so different results with leap years) echo Carbon::parse(''2000-02-15 12:00'')->floatDiffInYears(''2010-03-24 06:00''); // 10.100684931507 

关于夏令时（DST）的重要说明，默认情况下，PHP DateTime不考虑DST，这意味着例如，像2014年3月30日在伦敦这样仅23小时的一天将被计为24小时。

$date = new DateTime(''2014-03-30 00:00:00'', new DateTimeZone(''Europe/London'')); // DST off echo $date->modify(''+25 hours'')->format(''H:i''); // 01:00 (DST on, 24 hours only have been actually added) 

碳也遵循此行为，持续增加/减少/差异秒/分钟/小时。但是我们提供了 使用时间戳在实际时间中工作的方法：

$date = new Carbon(''2014-03-30 00:00:00'', ''Europe/London'');       // DST off echo $date->addRealHours(25)->format(''H:i''); // 02:00 (DST on) echo $date->diffInRealHours(''2014-03-30 00:00:00''); // 25 echo $date->diffInHours(''2014-03-30 00:00:00''); // 26 echo $date->diffInRealMinutes(''2014-03-30 00:00:00''); // 1500 echo $date->diffInMinutes(''2014-03-30 00:00:00''); // 1560 echo $date->diffInRealSeconds(''2014-03-30 00:00:00''); // 90000 echo $date->diffInSeconds(''2014-03-30 00:00:00''); // 93600 echo $date->diffInRealMilliseconds(''2014-03-30 00:00:00''); // 90000000 echo $date->diffInMilliseconds(''2014-03-30 00:00:00''); // 93600000 echo $date->diffInRealMicroseconds(''2014-03-30 00:00:00''); // 90000000000 echo $date->diffInMicroseconds(''2014-03-30 00:00:00''); // 93600000000 echo $date->subRealHours(25)->format(''H:i''); // 00:00 (DST off) // with float diff: $date = new Carbon(''2019-10-27 00:00:00'', ''Europe/Paris''); echo $date->floatDiffInRealHours(''2019-10-28 12:30:00''); // 37.5 echo $date->floatDiffInHours(''2019-10-28 12:30:00''); // 36.5 echo $date->floatDiffInRealMinutes(''2019-10-28 12:00:30''); // 2220.5 echo $date->floatDiffInMinutes(''2019-10-28 12:00:30''); // 2160.5 echo $date->floatDiffInRealSeconds(''2019-10-28 12:00:00.5''); // 133200.5 echo $date->floatDiffInSeconds(''2019-10-28 12:00:00.5''); // 129600.5 // above day unit, "real" will affect the decimal part based on hours and smaller units echo $date->floatDiffInRealDays(''2019-10-28 12:30:00''); // 1.5625 echo $date->floatDiffInDays(''2019-10-28 12:30:00''); // 1.5208333333333 echo $date->floatDiffInRealMonths(''2019-10-28 12:30:00''); // 0.050403225806452 echo $date->floatDiffInMonths(''2019-10-28 12:30:00''); // 0.049059139784946 echo $date->floatDiffInRealYears(''2019-10-28 12:30:00''); // 0.0042808219178082 echo $date->floatDiffInYears(''2019-10-28 12:30:00''); // 0.0041666666666667 

用同样的方法，你可以使用addRealX()和subRealX()任何设备上。

还具有特殊的过滤功能diffInDaysFiltered()，diffInHoursFiltered()和 diffFiltered()，以帮助您按天，小时或自定义间隔过滤差异。例如，计算两个实例之间的周末天数：

$dt = Carbon::create(2014, 1, 1);
$dt2 = Carbon::create(2014, 12, 31); $daysForExtraCoding = $dt->diffInDaysFiltered(function(Carbon $date) { return $date->isWeekend(); }, $dt2); echo $daysForExtraCoding; // 104 $dt = Carbon::create(2014, 1, 1)->endOfDay(); $dt2 = $dt->copy()->startOfDay(); $littleHandRotations = $dt->diffFiltered(CarbonInterval::minute(), function(Carbon $date) { return $date->minute === 0; }, $dt2, true); // true as last parameter returns absolute value echo $littleHandRotations; // 24 $date = Carbon::now()->addSeconds(3666); echo $date->diffInSeconds(); // 3665 echo $date->diffInMinutes(); // 61 echo $date->diffInHours(); // 1 echo $date->diffInDays(); // 0 $date = Carbon::create(2016, 1, 5, 22, 40, 32); echo $date->secondsSinceMidnight(); // 81632 echo $date->secondsUntilEndOfDay(); // 4767 $date1 = Carbon::createMidnightDate(2016, 1, 5); $date2 = Carbon::createMidnightDate(2017, 3, 15); echo $date1->diffInDays($date2); // 435 echo $date1->diffInWeekdays($date2); // 311 echo $date1->diffInWeekendDays($date2); // 124 echo $date1->diffInWeeks($date2); // 62 echo $date1->diffInMonths($date2); // 14 echo $date1->diffInYears($date2); // 1 

所有diffIn * Filtered方法都将1个可调用过滤器作为必需参数，将date对象作为可选的第二个参数（如果缺少），现在使用。您也可以将true作为第三个参数传递以获得绝对值。

要了解周/周末的高级信息，请使用以下工具：

echo implode('', '', Carbon::getDays());                       // Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday

$saturday = new Carbon(''first saturday of 2019''); $sunday = new Carbon(''first sunday of 2019''); $monday = new Carbon(''first monday of 2019''); echo implode('', '', Carbon::getWeekendDays()); // 6, 0 var_dump($saturday->isWeekend()); // bool(true) var_dump($sunday->isWeekend()); // bool(true) var_dump($monday->isWeekend()); // bool(false) Carbon::setWeekendDays([ Carbon::SUNDAY, Carbon::MONDAY, ]); echo implode('', '', Carbon::getWeekendDays()); // 0, 1 var_dump($saturday->isWeekend()); // bool(false) var_dump($sunday->isWeekend()); // bool(true) var_dump($monday->isWeekend()); // bool(true) Carbon::setWeekendDays([ Carbon::SATURDAY, Carbon::SUNDAY, ]); // weekend days and start/end of week or not linked Carbon::setWeekStartsAt(Carbon::FRIDAY); Carbon::setWeekEndsAt(Carbon::WEDNESDAY); // and it does not need neither to precede the start var_dump(Carbon::getWeekStartsAt() === Carbon::FRIDAY); // bool(true) var_dump(Carbon::getWeekEndsAt() === Carbon::WEDNESDAY); // bool(true) echo $saturday->copy()->startOfWeek()->toRfc850String(); // Friday, 31-Jan-20 00:00:00 UTC echo $saturday->copy()->endOfWeek()->toRfc850String(); // Wednesday, 05-Feb-20 23:59:59 UTC // Be very careful with those global setters, remember, some other // code or third-party library in your app may expect initial weekend // days to work properly. Carbon::setWeekStartsAt(Carbon::MONDAY); Carbon::setWeekEndsAt(Carbon::SUNDAY); echo $saturday->copy()->startOfWeek()->toRfc850String(); // Monday, 27-Jan-20 00:00:00 UTC echo $saturday->copy()->endOfWeek()->toRfc850String(); // Sunday, 02-Feb-20 23:59:59 UTC 

人类的差异

1 month ago与30天前相比，人类更容易阅读。这是大多数日期库中常见的功能，因此我想也将其添加到此处。该函数的唯一参数是要比较的另一个Carbon实例，当然，now()如果未指定，则默认为默认值。

此方法将在相对于实例和传入实例的差值之后添加一个短语。有4种可能性：

• 将过去的值与现在的默认值进行比较时：
  • 1小时前
  • 5个月前
• 将将来的值与现在的默认值进行比较时：
  • 从现在开始1小时
  • 从现在起5个月
• 将过去的值与另一个值进行比较时：
  • 1小时前
  • 5个月前
• 将将来的值与另一个值进行比较时：
  • 1小时后
  • 5个月后

您也可以通过CarbonInterface::DIFF_ABSOLUTE作为第二个参数，以去除改性剂前，从现在开始，等： diffForHumans($other, CarbonInterface::DIFF_ABSOLUTE)，CarbonInterface::DIFF_RELATIVE_TO_NOW 得到改性前或从现在开始，CarbonInterface::DIFF_RELATIVE_TO_OTHER得到改性剂 之前或之后，或者CarbonInterface::DIFF_RELATIVE_AUTO（默认模式），以获得修饰或者前 / 从现在开始，如果2第二个参数是空值或前 / 后如果没有。

true如果使用的语言环境可用，则可以作为第三个参数传递以使用简短语法diffForHumans($other, CarbonInterface::DIFF_RELATIVE_AUTO, true)。

可在1和6之间传递的数作为第四参数来获取在多个部分中的差异（更精确的差异）： diffForHumans($other, CarbonInterface::DIFF_RELATIVE_AUTO, false, 4)。

该$other实例可以是DateTime，Carbon实例或实现DateTimeInterface的任何对象，如果传递了字符串，则将对其进行解析以获取Carbon实例；如果null传递了字符串，Carbon::now()则将使用它。

为避免过多的参数并混合使用顺序，可以使用详细方法：

• shortAbsoluteDiffForHumans(DateTimeInterface | null $other = null, int $parts = 1)
• longAbsoluteDiffForHumans(DateTimeInterface | null $other = null, int $parts = 1)
• shortRelativeDiffForHumans(DateTimeInterface | null $other = null, int $parts = 1)
• longRelativeDiffForHumans(DateTimeInterface | null $other = null, int $parts = 1)
• shortRelativeToNowDiffForHumans(DateTimeInterface | null $other = null, int $parts = 1)
• longRelativeToNowDiffForHumans(DateTimeInterface | null $other = null, int $parts = 1)
• shortRelativeToOtherDiffForHumans(DateTimeInterface | null $other = null, int $parts = 1)
• longRelativeToOtherDiffForHumans(DateTimeInterface | null $other = null, int $parts = 1)

PS：$other和$parts参数可以根据需要交换。

// The most typical usage is for comments
// The instance is the date the comment was created and its being compared to default now()
echo Carbon::now()->subDays(5)->diffForHumans();               // 5 days ago echo Carbon::now()->diffForHumans(Carbon::now()->subYear()); // 11 months after $dt = Carbon::createFromDate(2011, 8, 1); echo $dt->diffForHumans($dt->copy()->addMonth()); // 1 month before echo $dt->diffForHumans($dt->copy()->subMonth()); // 1 month after echo Carbon::now()->addSeconds(5)->diffForHumans(); // 4 seconds from now echo Carbon::now()->subDays(24)->diffForHumans(); // 3 weeks ago echo Carbon::now()->subDays(24)->longAbsoluteDiffForHumans(); // 3 weeks echo Carbon::parse(''2019-08-03'')->diffForHumans(''2019-08-13''); // 1 week before echo Carbon::parse(''2000-01-01 00:50:32'')->diffForHumans(''@946684800''); // 50 minutes after echo Carbon::create(2018, 2, 26, 4, 29, 43)->longRelativeDiffForHumans(Carbon::create(2016, 6, 21, 0, 0, 0), 6); // 1 year 8 months 5 days 4 hours 29 minutes 43 seconds after 

您还可以$date->locale(''fr'')在diffForHumans（）调用之前使用来更改字符串的语言环境。有关更多详细信息，请参见本地化部分。

由于2.9.0 diffForHumans（）参数可以作为数组传递：

echo Carbon::now()->diffForHumans([''options'' => 0]); // 0 seconds ago
echo "\n"; // default options: echo Carbon::now()->diffForHumans([''options'' => Carbon::NO_ZERO_DIFF]); // 1 second ago echo "\n"; echo Carbon::now()->diffForHumans([''options'' => Carbon::JUST_NOW]); // just now echo "\n"; echo Carbon::now()->subDay()->diffForHumans([''options'' => 0]); // 1 day ago echo "\n"; echo Carbon::now()->subDay()->diffForHumans([''options'' => Carbon::ONE_DAY_WORDS]); // yesterday echo "\n"; echo Carbon::now()->subDays(2)->diffForHumans([''options'' => 0]); // 2 days ago echo "\n"; echo Carbon::now()->subDays(2)->diffForHumans([''options'' => Carbon::TWO_DAY_WORDS]); // before yesterday echo "\n"; // Options can be combined with pipes $now = Carbon::now(); echo $now->diffForHumans([''options'' => Carbon::JUST_NOW | Carbon::ONE_DAY_WORDS | Carbon::TWO_DAY_WORDS]); // just now echo "\n"; // Reference date for differences is `now` but you can use any other date (string, DateTime or Carbon instance): $yesterday = $now->copy()->subDay(); echo $now->diffForHumans($yesterday); // 1 day after echo "\n"; // By default differences methods produce "ago"/"from now" syntax using default reference (now), // and "after"/"before" with other references // But you can customize the syntax: echo $now->diffForHumans($yesterday, [''syntax'' => CarbonInterface::DIFF_RELATIVE_TO_NOW]); // 1 day from now echo "\n"; echo $now->diffForHumans($yesterday, [''syntax'' => 0]); // 1 day after echo "\n"; echo $yesterday->diffForHumans([''syntax'' => CarbonInterface::DIFF_ABSOLUTE]); // 1 day echo "\n"; // Combined with options: echo $now->diffForHumans($yesterday, [ ''syntax'' => CarbonInterface::DIFF_RELATIVE_TO_NOW, ''options'' => Carbon::JUST_NOW | Carbon::ONE_DAY_WORDS | Carbon::TWO_DAY_WORDS, ]); // tomorrow echo "\n"; // Other parameters: echo $now->copy()->subHours(5)->subMinutes(30)->subSeconds(10)->diffForHumans([ ''parts'' => 2, ]); // 5 hours 30 minutes ago echo "\n"; echo $now->copy()->subHours(5)->subMinutes(30)->subSeconds(10)->diffForHumans([ ''parts'' => 3, // Use -1 or INF for no limit ]); // 5 hours 30 minutes 10 seconds ago echo "\n"; echo $now->copy()->subHours(5)->subMinutes(30)->subSeconds(10)->diffForHumans([ ''parts'' => 3, ''join'' => '', '', // join with commas ]); // 5 hours, 30 minutes, 10 seconds ago echo "\n"; echo $now->copy()->subHours(5)->subMinutes(30)->subSeconds(10)->diffForHumans([ ''parts'' => 3, ''join'' => true, // join with natural syntax as per current locale ]); // 5 hours, 30 minutes and 10 seconds ago echo "\n"; echo $now->copy()->subHours(5)->subMinutes(30)->subSeconds(10)->locale(''fr'')->diffForHumans([ ''parts'' => 3, ''join'' => true, // join with natural syntax as per current locale ]); // il y a 5 heures, 30 minutes et 10 secondes echo "\n"; echo $now->copy()->subHours(5)->subMinutes(30)->subSeconds(10)->diffForHumans([ ''parts'' => 3, ''short'' => true, // short syntax as per current locale ]); // 5h 30m 10s ago // ''aUnit'' option added in 2.13.0 allows you to prefer "a day", "an hour", etc. over "1 day", "1 hour" // for singular values when it''s available in the current locale echo $now->copy()->subHour()->diffForHumans([ ''aUnit'' => true, ]); // an hour ago // Before 2.9.0, you need to pass parameters as ordered parameters: // ->diffForHumans($other, $syntax, $short, $parts, $options) // and ''join'' was not supported 

如果参数被省略或设置为null，则仅Carbon::NO_ZERO_DIFF启用。可用的选项有：

• Carbon::ROUND/ Carbon::CEIL/ Carbon::FLOOR（默认无）：仅3中的一个可在同一时间使用（其他被忽略），它需要''parts''进行设置。默认情况下，一旦差异按''parts''要求进行设置，然后忽略所有剩余单位。
  • 如果Carbon::ROUND启用，将对剩余的单位求和，并且如果它们 > = diff的最后一个单位的0.5，则此单位将舍入为上限值。
  • 如果Carbon::CEIL启用，则将对剩余的单位求和，并且如果它们 大于 diff的最后一个单位的0，则此单位将四舍五入为最大值。
  • 如果Carbon::FLOOR启用，则最后一个差异单元将四舍五入。它与默认行为没有什么区别，diffForHumans()因为该间隔不会溢出，但与CarbonInterval::forHumans()（和可能长达60分钟或更长，24小时或更长时间的未经检查的间隔）一起使用时，可能需要使用此选项 。例如： CarbonInterval::make(''1 hour and 67 minutes'')->forHumans([''parts'' => 1])return "1 hour"而 CarbonInterval::make(''1 hour and 67 minutes'')->forHumans([''parts'' => 1, ''options'' => Carbon::FLOOR]) return "2 hours"。
• Carbon::NO_ZERO_DIFF （默认启用）：将空diff变为1秒
• Carbon::JUST_NOW 默认情况下处于禁用状态）：将diff从现在到现在变成“ just now”
• Carbon::ONE_DAY_WORDS （默认情况下处于禁用状态）：将“从现在/前1天”更改为“昨天/明天”
• Carbon::TWO_DAY_WORDS （默认情况下处于禁用状态）：将“从现在/前2天”更改为“昨天/之前”
• Carbon::SEQUENTIAL_PARTS_ONLY （默认情况下处于禁用状态）：将仅保留间隔的第一个单位序列，例如，如果差异将是“ 2周1天34分钟12秒”，因为日和分钟不是连续的单位，则将得到： 2周1天”。

使用管道运算符一次启用/禁用多个选项，例如： Carbon::ONE_DAY_WORDS | Carbon::TWO_DAY_WORDS

你也可以使用Carbon::enableHumanDiffOption($option)， Carbon::disableHumanDiffOption($option)，Carbon::setHumanDiffOptions($options)更改默认选项，并Carbon::getHumanDiffOptions() 获得默认选项，但你应该避免使用它为静态的，可能与其他的部分代码/第三方库调用冲突。

出于语义目的提供了别名和反向方法：

• from($other = null, $syntax = null, $short = false, $parts = 1, $options = null) （diffForHumans的别名）
• since($other = null, $syntax = null, $short = false, $parts = 1, $options = null) （diffForHumans的别名）
• to($other = null, $syntax = null, $short = false, $parts = 1, $options = null) （相反的结果，交换之前和将来的差异）
• until($other = null, $syntax = null, $short = false, $parts = 1, $options = null) （至的别名）
• fromNow($syntax = null, $short = false, $parts = 1, $options = null)（除非第一个参数是a DateTimeInterface，否则将省略from与第一个参数的别名，除非现在使用第一个参数），用于语义用法：生成一个类似“从现在开始3小时”的字符串，并带有将来的日期
• ago($syntax = null, $short = false, $parts = 1, $options = null) （fromNow的别名），用于语义用法：生成一个类似“ 3小时前”的字符串，其中带有过去的日期
• toNow($syntax = null, $short = false, $parts = 1, $options = null) （省略了第一个参数的to的别名，现在改为使用）
• timespan($other = null, $timezone = null)调用diffForHumans并带有选项join = '', ''（以逗号 分隔）， syntax = CarbonInterface::DIFF_ABSOLUTE（没有“ ago” /“从现在开始” /“之前” /“之后”这句话）， options = CarbonInterface::NO_ZERO_DIFF（没有“仅此刻” /“昨天” /“明天”这句话）， parts = -1（没有限制）在此模式下，您无法更改选项，但可以传递一个可选日期以与之比较，或者传递一个字符串+时区以进行解析以获取该日期。

修饰符

这组方法对当前实例执行有用的修改。他们中的大多数人的名字都是不言自明的……至少应该如此。您还会注意到，对于大于天的单位，startOfXXX（），next（）和previous（）方法将时间设置为00:00:00，而endOfXXX（）方法将时间设置为23:59:59。

唯一略有不同的是average()功能。它将您的实例移动到其自身与所提供的Carbon参数之间的中间日期。

强大的本机modify() 方法DateTime可供使用。但是，我们还提供了它的增强版本： change()它允许一些附加的语法，例如"next 3pm"和，它们在->next()and 内部调用->previous()。
