PHP AJAX 乱码 解决办法

AJAX支持UTF8
先在PHP页上加个header(”content-type:text/html; charset=utf-8″);
告诉网页这个实现的编码是UTF-8
然后把要输出的内容用$test = iconv('gbk', ‘utf-8′, $test);转一下编码
然后再输出即可
例如：
<?php
header(”content-type:text/html; charset=utf-8″);
$test=”我是中文”;
$test = iconv('gb2312', ‘utf-8′,$ test);
echo $test;
?>
---------------------------------------------------------------
在此顺便附加一个由js的escape加密传送过来的解密函数unescape($str)
<?
function unescape($str) {
$str = rawurldecode($str);
preg_match_all("/%u.{4}|&#x.{4};|&#\d+;|&#\d+?|.+/U",$str,$r);
$ar = $r[0];
foreach($ar as $k=>$v) {
if(substr($v,0,2) == "%u")
$ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,-4)));
elseif(substr($v,0,3) == "&#x")
$ar[$k] = iconv("UCS-2","UTF-8",pack("H4",substr($v,3,-1)));
elseif(substr($v,0,2) == "&#") {
$ar[$k] = iconv("UCS-2","UTF-8",pack("n",preg_replace("/[^\d]/","",$v)));
}
}
return join("",$ar);
}
?>
