PHP实现Javascript中的escape及unescape函数代码分享，escapeunescape

这个类相当好用.作用么,PHP做JSON传递GBK字符,比如中文,日文,韩文神马的Unicode最合适不过了..

1){// 多字节字符 
        $return.='%u'.strtoupper(bin2hex(mb_convert_encoding($str,'UCS-2',$encoding)));
      }else{
        $return.='%'.strtoupper(bin2hex($str));
      }
    }
    return$return;
  }
  
  functiongb2utf8($string,$encoding='utf-8',$from_encode='gb2312')
  {
    returnmb_convert_encoding($string,$encoding,$from_encode);
  }
  
}
?>

google code 上找到的另外一个类似脚本

=127)
            {
                $tmpString=bin2hex(iconv("gbk","ucs-2",substr($str,$i,2)));
                $tmpString=substr($tmpString,2,2).substr($tmpString,0,2);
                $retrunString.="%u".$tmpString;
                $i++;
            }else{
                $retrunString.="%".dechex(ord($str[$i]));
            }
        }
        return$retrunString;
    }
 
 
    functionescape($str)
    {
        preg_match_all("/[\x80-\xff].|[\x01-\x7f]+/",$str,$r);
        $ar=$r[0];
        foreach($aras$k=>$v)
        {
            if(ord($v[0])$v)
        {
            if(substr($v,0,2)=="%u")
                $ar[$k]=iconv("UCS-2","UTF-8",pack("H4",substr($v,-4)));
            elseif(substr($v,0,3)=="")
                $ar[$k]=iconv("UCS-2","UTF-8",pack("H4",substr($v,3,-1)));
            elseif(substr($v,0,2)=="")
            {
                //echo substr($v,2,-1)."";
                $ar[$k]=iconv("UCS-2","UTF-8",pack("n",substr($v,2,-1)));
            }
        }
        returnjoin("",$ar);
    }
 
?>
