        $vvv='{"subscribe":1,"openid":"ol2E7uLeDEi4VCBwrXI0KRwcvnyo","nickname":"xhm","sex":2,"language":"zh_CN","city":"mñW3","province":"^N","country":"","headimgurl":"http:\/\/wx.qlogo.cn\/mmopen\/PiajxSqBRaELiaLZZTltPhZobM3QcvGyGgRXnAlcPm8iaoWQWvuNuIFZk3kOOeNCQok1W4l6zashSAMfMSiasN4eZhbuib4NXuQNmQuFMn2XBd9M\/0","subscribe_time":1458906765,"remark":"","groupid":0}';        var_dump(json_decode($vvv,true));exit;
Copy after login

转不了，返回值为null,是因为city和province的值 是特殊符号，请问怎样处理？


回复讨论(解决方案)

特殊符号进行转意

应该先解决city和province乱码的问题，再去json_decode，因为手册上说，json_decode必须是utf-8的编码格式。可以尝试用iconv相关函数试试

iconv试了，不行

city = 深圳
province = 广东 

$vvv = iconv('ucs-2', 'utf-8', $vvv);var_dump(json_decode($vvv,true));
Copy after login
Copy after login
需要注意的是，你的 $vvv 必须是原始渠道的来的数据，而不是你贴出的经复制粘贴的数据
原始的 unicode 数据，经过复制粘贴，就无法再恢复了

"city":"mñW3","province":"^N
有不是utf8的数据，需要先处理

city = 深圳
province = 广东 

$vvv = iconv('ucs-2', 'utf-8', $vvv);var_dump(json_decode($vvv,true));
Copy after login

不行啊，我这数据是从微信接口那里得来的，我没有处理过就json_decode了，但是微信那里有些资料的确是有乱码的
