decodejsonphp

一、函数简介
1、此函数有四个参数，一般在使用时会用到前两个，具体的参数可以看手册。

2、第一个参数是json格式的字符串，第二个参数是boolean值(false转化成对象，true转化成数组，默认false)，如果转化失败返回null。

二、遇到的问题
在项目中调用了java写的一个web服务，返回的数据是"{'stauts':'1','message':'充值成功'}"。

程序接到后用json_decode把结果转化成数组，但转化的结果是null，太奇怪了。

看了一下手册，在手册中发现了下面的说明，一下就明白了。

把返回的结果改成'{"stauts":"1","message":"充值成功"}'再转化数组就OK了。
