如用户信息某一字段存在特殊字符，这导致JSON_DECODE返回NULL，现对微信服务器请求结果进行编码替换后在进行解析。 示例代码： $str = '{"subscribe":1,"openid":"o7TC3v_zvuxmuRPU6YeBOD6cz0Ng","nickname":"文文","sex":2,"language":"zh_CN","city":"S�Y4","province":"Q���Sä","country":"","headimgurl":"http://wx.qlogo.cn/mmopen/0dhrpQA7Vn64H2u2zApyiaicEg4hk0UCIqrJP0EcRDh1z108ARaaWUYIDfmLvBXicxGpo4uWej1PjsdMZcWIdPQ7TJehRnLWaJD/0","subscribe_time":1482894792,"remark":"","groupid":0,"tagid_list":[]}'; json_decode($str, true); 返回NULL 主要原因是city字段含有特殊符合或表情符号
