PHP json_decode函数详细解析
本篇文章主要是对PHP json_decode函数进行了介绍,需要的朋友可以过来参考下,希望对大家有所帮助
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。
