有个疑问，你找个gbk的json串是如何生成的？
具体转换方法，很简单，把字符串转换为utf8编码，在调用json_decode既可。
具体原因可以查看博客 
http://www.bo56.com/%E5%9C%A8php%E4%B8%AD%E5%A6%82%E4%BD%95%E4%BD%BF%E7%94%A8json_decode%E8%A7%A3%E6%9E%90gbk%E7%BC%96%E7%A0%81%E7%9A%84json%E5%AD%97%E7%AC%A6%E4%B8%B2/

这是直接从网页用curl抓取的，要是自己用json_ecode生成我也知道很简单

现在问题就是这个用gbk编码的数据已经存在了，怎样去解码

<?php$json = '"信海龙"'; //一个符合json格式的gbk编码串var_dump(json_decode($str)); //输出NULL$str = mb_convert_encoding($json, "utf8", "gbk");var_dump(json_decode($str)); //输出 string(9) "信海龙"?>

为什么转换为utf8编码后，就可以正常使用json_decode，参加日志
http://www.bo56.com/%E5%9C%A8php%E4%B8%AD%E5%A6%82%E4%BD%95%E4%BD%BF%E7%94%A8json_decode%E8%A7%A3%E6%9E%90gbk%E7%BC%96%E7%A0%81%E7%9A%84json%E5%AD%97%E7%AC%A6%E4%B8%B2/

现在问题就是这个用gbk编码的数据已经存在了，怎样去解码
那你就把数据用utf-8 编码就可以了

$s=你的json串print_r(json_decode(iconv('gbk','utf-8',$s),true));

晕个，写过无数种转换了，一直都没成功，现在发现原来是淘宝U站的问题，一放到外站，随便怎么写都ok能正确解码的，晕死
还是谢谢各位
