模仿JAVASCRIPT的ESCAPE和UNESCAPE函数的功能

<?
class coding {
     //模仿JAVASCRIPT的ESCAPE和UNESCAPE函数的功能
    function unescape($str){
        $text = preg_replace_callback("/%u[0-9A-Za-z]{4}/",array( &$this, 'toUtf8'),$str);

            if($val < 0x7F){ // 0000-007F
                $c .= chr($val);
            }elseif($val < 0x800) { // 0080-0800
                $c .= chr(0xC0 | ($val / 64));

函数描述及例子


在不支持iconv的空间上模仿javascript的编码
可以用来做AJAX传递中文用

$coding=new coding();
$string_escape=$coding->escape("四川");
$string_unescape=$coding->unescape("%u56DB%u5DDD");
echo $string_escape.$string_unescape
