function utf8_urldecode($str) 

{
$str = preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($str));
return html_entity_decode($str,null,‘UTF-8‘);;
}

function ConvertUTF8ToGB2312($str)
{
return iconv("UTF-8","GB2312//IGNORE",$str);
}

function ConvertGB2312ToUTF8($str)
{
return iconv("GB2312","UTF-8//IGNORE",$str);
}

php處理環境是utf-8的, jquery所在網頁也是的utf-8的, jquery post的中文資料以%u開頭, 需要將這個code轉寄到另一台接收gb2312字元的web網站

if(isset($_REQUEST["code"])){    //解碼    $tmp = utf8_urldecode($_REQUEST["code"]);    //utf-8轉gb2312    $tmp = ConvertUTF8ToGB2312($tmp);    //編碼    $tmp = urlencode($tmp);    $AppendPara .= "&code=" . $tmp;}else{    $AppendPara .= "&code=";}
