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)); "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));
