让PHP解码JAVASCRIPT的escape编码

      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

phperz.com

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);
  }

function unescape($str) {
  $str = rawurldecode($str);
  preg_match_all("/%u.|&#x.;|&#\d+;|.+/U",$str,$r);
  $ar = $r[0];
  foreach($ar as $k=>$v) {
    if(substr($v,0,2) == "%u")
      $ar[$k] = iconv("UCS-2","GBK",pack("H4",substr($v,-4)));
    elseif(substr($v,0,3) == "&#x")
      $ar[$k] = iconv("UCS-2","GBK",pack("H4",substr($v,3,-1)));
    elseif(substr($v,0,2) == "&#") {
      $ar[$k] = iconv("UCS-2","GBK",pack("n",substr($v,2,-1)));
    }
  }
  return join("",$ar);
}
