json_encode,汉字问题

本帖最后由 xtjsxtj 于 2015-04-09 21:50:26 编辑 按网上大部分说法是先将汉字urlencode,json_encode后再urldecode

这样,有个问题是,假如原来:
$arr = array ('a'=>urlencode('脚本,之家'));   //简体中文BGK编码
echo urldecode(json_encode($arr));

则结果为{"a": "脚本,之家"}
这是一个非法的json串,json_decode是解不开的

大家是如何这样解决这个问题的

是不是都转换成了utf8编码了

假如这个json串还要做url请求的参数,还要urlencode,这个又要怎样处理呢?
按utf8 先json_encode,然后再对整个json串做urlencode吗?
------解决思路----------------------
首先 gbk 的 {"a": "脚本,之家"} 并不是非法的 json 串
JSON 从来就没有要求过值域的字符集

至于不能被 json_decode 解开,是因为函数开发者认为 php 收到的 json 串都是由 XMLHttpRequest 发来的,而 XMLHttpRequest 总是以 utf-8 编码发送数据。因此就没有不要再在函数中辨别字符集了
从而造成 php 的 json 函数只支持 utf-8 的情况

既然已经这样了,那你就得去适应这个环境
