二者的差异可以可参考:
http://php.weblogs.com/php_jscript_vbscript_1

节录如下:

PHP:
urlencode( ) All punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding. Spaces converted to +.

urldecode( )All punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding. Spaces converted to +.

Javascript:
Javascript(str) All spaces, punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding

那要如何用 PHP 来读取 escape() 编码过的字符串呢?

可以用以下的方式来读取 (范例为 Unicode 解译为 big5)

修改自:http://vivian.stripper.jp/index.php?itemid=100

$str = uniDecode($str,'big-5');

function uniDecode($str,$charcode){

  $text = preg_replace_callback("/%u[0-9A-Za-z]{4}/",toUtf8,$str);

  return mb_convert_encoding($text, $charcode, 'utf-8');

}

function toUtf8($ar){

  foreach($ar as $val){

    $val = intval(substr($val,2),16);

    if($val < 0x7F){        // 0000-007F

        $c .= chr($val);

    }elseif($val < 0x800) { // 0080-0800

        $c .= chr(0xC0 | ($val / 64));

        $c .= chr(0x80 | ($val % 64));

    }else{                // 0800-FFFF

        $c .= chr(0xE0 | (($val / 64) / 64));

        $c .= chr(0x80 | (($val / 64) % 64));

        $c .= chr(0x80 | ($val % 64));

    }

  }

  return $c;

}
