让PHP解码JAVASCRIPT的escape编码可以使用以下两个方法，一个是编码，一个是解码，要想正确运行以下两个函数需要为PHP添加配置iconv模块 php程序员站
添加配置iconv模块 php程序员之家
function escape($str) {
preg_match_all("/[\x80-\xff].|[\x01-\x7f]+/",$str,$r);
$ar = $r[0];
foreach($ar as $k=>$v) {
if(ord($v[0]) < 128)
$ar[$k] = rawurlencode($v);
else
//$ar[$k] = "%u".bin2hex(iconv("GB2312","UCS-2",$v));
$ar[$k] = "%u".bin2hex(iconv("GBK","UCS-2",$v));//这里更正
}
return join("",$ar);
