PHP：json解码限制（php json解码）
拿这个代码：
$json = file_get_contents($this->url,true);
$decode = json_decode($json,true);
foreach ($decode as $key => $value) {
...
}
很简单,呃？
通过一个带有多达500个数组元素的$json ….正常工作！
超过该限制……错误是：
Warning: Invalid argument supplied for foreach() in
/c/website/retriever/WsGlassRetriever.PHP on line 19
该函数的参数是否有一些内存限制？
我在文档中没有发现任何相关内容.我的版本是PHP 5.2.17-rnx1.1,带有Suhosin-Patch 0.9.7(cli)
如果JSON语法中存在错误,json_decode将返回NULL.我刚刚成功测试了1000个元素的数组,它运行得很好.
仔细检查您的JSON格式是否正确.即使是单引号而不是双引号,或者忘记将属性名称放在引号中,或者使用32-127范围之外的字符而没有在UTF-8中正确编码它的东西,也会导致这些问题.
GO json解码和编码
json编码
func Marshal(v interface{}) ([]byte, error)
package main
import (
"encoding/json"
"fmt"
)
//tag中的第一个参数是用来指定别名
//比如Name 指定别名为 username `json:"username"`
//如果不想指定别名但是想指定其他参数用逗号来分隔
//omitempty 指定到一个field时
//如果在赋值时对该属性赋值 或者 对该属性赋值为 zero value
//那么将Person序列化成json时会忽略该字段
//- 指定到一个field时
//无论有没有值将Person序列化成json时都会忽略该字段
//string 指定到一个field时
//比如Person中的Count为int类型 如果没有任何指定在序列化
//到json之后也是int 比如这个样子 "Count":0
//但是如果指定了string之后序列化之后也是string类型的
//那么就是这个样子"Count":"0"
type Person struct {
Name string `json:"username"`
Age int
Gender bool `json:",omitempty"`
Profile string
OmitContent string `json:"-"`

func main() {

fmt.Println(p.Name, ":", p.Age, ":", p.Gender)
// unmarshal to slice-struct
var ps []Person
var aJson = `[{"Name":"junbin", "Age":21, "Gender":true},
{"Name":"junbin", "Age":21, "Gender":true}]`
json.Unmarshal([]byte(aJson), &ps)
//result --> [{junbin 21 true} {junbin 21 true}] len is 2
fmt.Println(ps, "len is", len(ps))
// unmarshal to map[string]interface{}
var obj interface{} // var obj map[string]interface{}
json.Unmarshal([]byte(str), &obj)
m := obj.(map[string]interface{})
//result --> junbin : 21 : true
fmt.Println(m["Name"], ":", m["Age"], ":", m["Gender"])
//unmarshal to slice
var strs string = `["Go", "Java", "C", "Php"]`
var aStr []string
json.Unmarshal([]byte(strs), &aStr)
//result --> [Go Java C Php] len is 4
fmt.Println(aStr, " len is", len(aStr))

jQuery JSON解码(PHP到Javascript)
我正在尝试制作一个自动完成脚本.我通过JSON传递变量,然后我不知道如何继续解码JSON.
这是我得到的JSON代码的一个例子,我想在一个简单的javascript数组中转换它：
[{"ID":"1","name":"Amateur astronomy \r"},{"ID":"2","name":"Amateur microscopy \r"},{"ID":"173","name":"Amateur radio \r"},{"ID":"299",{"ID":"349","name":"Amateur theater \r"}]
解决方法
执行此操作的标准JavaScript方法是使用
JSON.parse：
var myArray = JSON.parse(someJSONString);
为了与缺少内置JSON对象的旧浏览器兼容,jQuery具有its own method：
var myArray = jQuery.parseJSON(someJSONString);
从jQuery / 3.0开始,这种方法已被弃用.
json.loads() json解码
有些json数据里面套着json 一次json.loads()后还是会有数据是json格式

}比如这种数据,我需要拿到数据好,在进行一次json.loads()
import json
a = "[{\"content\":\"t086921wjm7\",\"thumb\":\"http:\\/\\/puui.qpic.cn\\/qqvideo_ori\\/0\\/t086921wjm7_496_280\\/0\",\"type\":\"1\"},{\"content\":\"v0863nclm02\",\"thumb\":\"http:\\/\\/puui.qpic.cn\\/qqvideo_ori\\/0\\/v0863nclm02_496_280\\/0\",\"type\":\"1\"},{\"content\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/4513950d71595f5adf9081f377e7a774.jpg\\/1000\",\"thumb\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/4513950d71595f5adf9081f377e7a774.jpg\\/1000\",\"type\":\"0\"},{\"content\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/a6189769d199568691cf64f880dab4eb.jpg\\/1000\",\"thumb\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/a6189769d199568691cf64f880dab4eb.jpg\\/1000\",\"type\":\"0\"},{\"content\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/7a6ac3f0636f277aec94a7519857c156.jpg\\/1000\",\"thumb\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/7a6ac3f0636f277aec94a7519857c156.jpg\\/1000\",\"type\":\"0\"},{\"content\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/b04dec6f35f10074b2b73eb7be187251.jpg\\/1000\",\"thumb\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/b04dec6f35f10074b2b73eb7be187251.jpg\\/1000\",\"type\":\"0\"},{\"content\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/4f7712ff9d48c5c6b0987580eb79805e.jpg\\/1000\",\"thumb\":\"http:\\/\\/p.qpic.cn\\/wegame\\/0\\/4f7712ff9d48c5c6b0987580eb79805e.jpg\\/1000\",\"type\":\"0\"}]"
print(json.loads(a))
for i in json.loads(a):
print(i)
JSOND--一个更优的PHP JSON解析器
jsond：一个更优的php json解析器
首先，我们先来看看性能测试数据：
| 01 | STR: { "i" : 23, "array" : [1, null, false, true, [ "aha" , "baba" , 23, { "test" : 23}]]} |
| 02 | JSON: time for 100000 iterations: 0.238321 |
| 03 | JSOND: time for 100000 iterations: 0.236436 |
04
| 05 | STR: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] |
| 06 | JSON: time for 100000 iterations: 0.110764 |
| 07 | JSOND: time for 100000 iterations: 0.134212 |
08
| 09 | STR: { "a" : 23.2234232} |
| 10 | JSON: time for 100000 iterations: 0.078458 |
| 11 | JSOND: time for 100000 iterations: 0.055479 |

可以看到在大数据量的时候jsond的速度比json快多了。
