PHP实现的浏览器检查类 phpstorm浏览器设置 php 模拟浏览器 php输出图片到浏览

本文实例讲述了php实现的浏览器检查类。分享给大家供大家参考，具体如下：

UA  = getenv(HTTP_USER_AGENT);
  $preparens = "";
  $parens = "";
  $i = strpos($this->UA,"(");
  if ($i >= 0)  {
    $preparens = trim(substr($this->UA,0,$i));
    $parens = substr($this->UA,$i+1,strlen($this->UA));
    $j = strpos($parens,")");
    if($j>=0) {

    }
  }
  else  {

    $this->BROWSER = "Opera";
    $leftover=substr($browVer,strlen("Opera")+1,strlen($browVer));
  }
  $leftover = trim($leftover);
  $i=strpos($leftover," ");
  if($i > 0)  {
    $this->VERSION = substr($leftover,0,$i);
  }
  else  {
    $this->VERSION = $leftover;
  }
  $j = strpos($this->VERSION,".");
  if($j >= 0)  {

12.21 php-fpm的pool

为了避免因多站点使用同一个pool时因一个站点故障导致pool出问题，进而影响使用同一个pool的其他站点的正常运行，要对每个站点配置一个单独的pool。

为php-fpm增加pool

[root@cham002 cham.com]# cd /usr/local/php-fpm/etc/
[root@cham002 etc]# ls
pear.conf  php-fpm.conf  php-fpm.conf.default  php.ini
[root@cham002 etc]# cat php-fpm.conf
[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
#listen = /tmp/php-fcgi.sock
listen = 127.0.0.1:9000
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
[root@cham002 etc]# vi !$
vi php-fpm.conf

[champin.com]
#listen = /tmp/champin.sock
listen = 127.0.0.1:9000
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024

语法检测：

[root@cham002 etc]# /usr/local/php-fpm/sbin/php-fpm -t
[09-Jan-2018 00:36:35] ERROR: [pool champin.com] unable to set listen address as it''s already used in another pool ''www''
[09-Jan-2018 00:36:35] ERROR: failed to post process the configuration
[09-Jan-2018 00:36:35] ERROR: FPM initialization failed

原因是我以为名字不对，后来换了名字还是不行，仔细看配置文件发现原因

为站点配置pool

[root@cham002 etc]# cd /usr/local/nginx/conf/vhost/
[root@cham002 vhost]# ls
aaa.com.conf  load.conf  proxy.conf  ssl.conf  test.com.conf
[root@cham002 vhost]# vim aaa.com.conf 

server
{
    listen 80 default_server;
    server_name aaa.com;
    index index.html index.htm index.php;
    root /data/wwwroot/default;
 location ~ \.php$
    {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/champ.sock;
       #fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/default$fastcgi_script_name;
    }

}

说明： 把fastcgi_pass地址改为和php-fpm.conf中一样的地址就可以。

 

添加php-fpm.conf子配置文件

为了便于管理，可以将php-fpm中的每个pool单独进行管理。进行如下操作，添加php-fpm子配置文件：

[root@cham002 vhost]# cd /usr/local/php-fpm/etc/
[root@cham002 etc]# vim php-fpm.conf
[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
include = etc/php-fpm.d/*.conf

说明： 在全局变量版块添加参数“include = etc/php-fpm.d/*.conf”。然后可以清除php-fpm配置文件中其他参数，再到php-fpm.d目录下进行单独设置。

[root@cham002 vhost]# cd /usr/local/php-fpm/etc/
[root@cham002 etc]# mkdir php-fpm.d
[root@cham002 etc]# cd php-fpm.d/
[root@cham002 php-fpm.d]# vim www.conf
[www]
listen = /tmp/php-fcgi.sock
#listen = 127.0.0.1:9000
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
[root@cham002 php-fpm.d]# ls
www.conf

[root@cham002 php-fpm.d]# vim champ.conf
[champ]
listen = /tmp/champ.sock
#listen = 127.0.0.1:9000
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 500
rlimit_files = 1024
[root@cham002 php-fpm.d]# ls

5、PHP-将浮点数转为整数 php 浮点数比较 php 浮点数精度 php 浮点数格式

5、PHP-将浮点数转为整数 php 浮点数比较 php 浮点数精度 php 浮点数格式

1、使用强制类型转换

首先PHP支持如下所示的数据类型：

<span>1. </span>Integer    (整数)
<span>2. </span>Float      (浮点数)
<span>3. </span>String     (字符串)
<span>4. </span>Boolean    (布尔值)
<span>5. </span>Array      (数组)
<span>6. </span>Object     (对象)
登录后复制

此外还有两个特殊的类型：NULL(空)、resource（资源）。

注：
1. 没有被赋值、已经被重置或者被赋值为特殊值NULL的变量就是NULL类型的变量。
2. 特定的内置函数（例如数据库函数）将返回resource类型的变量。

接着可以使用类似C语言的强制类型转换，例如

<span><?php </span><span>$a</span>=<span>6.66666</span>;
<span>$b</span>=(integer)<span>$a</span>;
<span>echo</span><span>$b</span>;</span>
登录后复制

将输出一个6，直接舍去了小数部分

立即学习“PHP免费学习笔记（深入）”；

2、使用float floor ( float value) 函数

舍去法取整，返回不大于 value 的下一个整数，将 value 的小数部分舍去取整。floor() 返回的类型仍然是 float，因为float 值的范围通常比 integer 要大。

echo <span>floor</span>(<span>4.3</span>);   <span>// 输出4 </span>
echo <span>floor</span>(<span>9.999</span>); <span>// 输出9</span>
登录后复制

3、使用float ceil ( float value) 函数

进一法取整，返回不小于 value 的下一个整数，value 如果有小数部分则进一位。ceil() 返回的类型仍然是 float，因为float 值的范围通常比 integer 要大。

echo <span>ceil</span>(<span>4.3</span>);    <span>// 输出5 </span>
echo <span>ceil</span>(<span>9.999</span>);  <span>// 输出10</span>
登录后复制

4、使用float round ( float val [, int precision])函数

对浮点数进行四舍五入，返回将 val 根据指定精度 precision（十进制小数点后数字的数目）进行四舍五入的结果。precision 也可以是负数或零（默认值）。

echo <span>round</span>(<span>3.4</span>);         <span>// 输出3 </span>
echo <span>round</span>(<span>3.5</span>);         <span>// 输出4 </span>
echo <span>round</span>(<span>3.6</span>);         <span>// 输出4 </span>
echo <span>round</span>(<span>3.6</span>, <span>0</span>);      <span>// 输出4 </span>
echo <span>round</span>(<span>1.95583</span>, <span>2</span>);  <span>// 输出1.96 </span>
echo <span>round</span>(<span>1241757</span>, -<span>3</span>); <span>// 输出1242000 </span>
echo <span>round</span>(<span>5.045</span>, <span>2</span>);    <span>// 输出5.04 </span>
echo <span>round</span>(<span>5.055</span>, <span>2</span>);    <span>// 输出5.06</span>

'').addClass(''pre-numbering'').hide(); $(this).addClass(''has-numbering'').parent().append($numbering); for (i = 1; i '').text(i)); }; $numbering.fadeIn(1700); }); });

Brew 安装 php，但“php -v”返回 MacOS 原生 php 的信息

Brew 安装 php，但“php -v”返回 MacOS 原生 php 的信息

删除系统二进制文件通常不是一个好主意。相反，您可以在 ~/.zshrc 文件中添加别名。在文件末尾添加：

alias php="/usr/local/bin/php"
,

解决方案是将其放入 ~/.bash-profile

export PATH=/usr/local/bin:$PATH

重启电脑，它准备好了，现在当我php -v

file_get_contents('php://input') 不适用于 Laravel+Octane / Swoole PHP 代码使用 PHP-FPM使用 Octane+Swoole

如何解决file_get_contents(''php://input'') 不适用于 Laravel+Octane / Swoole PHP 代码使用 PHP-FPM使用 Octane+Swoole？

我正在从 Laravel 8 迁移到 Laravel 8 + Octane / Swoole。一切正常，但 PHP://input 始终为空。另外，我检查 $_POST 和 $_SERVER 值。

file_get_contents(''PHP://input'') 被 AWS SNS Message Validator 使用。

阅读 PHP://input 的任何替代方案？

PHP 代码

echo "PHP://input: ".file_get_contents(''PHP://input'');

使用 PHP-FPM

$ curl -i -X POST --data "dataaaa" https://example.com/aws/sns/webhook
PHP://input: dataaaa

使用 Octane+Swoole

$ curl -i -X POST --data "dataaaa" https://example.com/aws/sns/webhook
PHP://input:

解决方案：PSR-7 请求

php://input

当然，对于辛烷值，Laravel PSR-7 requests 需要 use Psr\Http\Message\RequestInterface; public function sesSubscriptionWebhook(RequestInterface $request) { // $input = file_get_contents(''php://input''); // dont work on swoole $input = $request->getBody(); } 和 symfony/psr-http-message-bridge。

此外，如果您的问题与 AWS SES 相关，您需要将 nyholm/psr7 更改为 Message::fromRawPostData()。
