Answer 1

ajax提交的：where = encodeURIComponent(where);
然后php：  $condition['username'] = @iconv( "UTF-8","GBK", $array[2]);
在线等待，求解决！

Answer 2

接收的参数用urldecode解码试试

Answer 3

你的客户端用的是 jquery 吧？
jq 的 ajax 是不需要自己做 url 编码的
既然你已经有 where = encodeURIComponent(where); 了
那么就需要自己再做一次 url 解码
$condition['username'] = iconv( "UTF-8","GBK", uredecode($array[2]));

Answer 4

解决了！
用iconv 有时候失效了！ 用以下代码：<?
$a=urldecode("%E5%90%89%E6%9E%97");
$a=mb_convert_encoding($a, 'GB2312', 'UTF-8'); 
echo $a;
?>
