    /**
     *  获得当前的页面文件的url
     *
     * @access    private
     * @return    string
     */
    function GetCurUrl()
    {
        if(!empty($_SERVER["REQUEST_URI"]))
        {
            $nowurl = $_SERVER["REQUEST_URI"];
            $nowurls = explode("?",$nowurl);
            $nowurl = $nowurls[0];
        }
        else
        {
            $nowurl = $_SERVER["PHP_SELF"];
        }
        return $nowurl;
    }

<?php

class abc{

    var $nowurl;

    function TagGetCurUrl()
    {
        if(!empty($_SERVER["REQUEST_URI"]))
        {
            $nowurl = $_SERVER["REQUEST_URI"];
        }
        else
        {
            $nowurl = $_SERVER["PHP_SELF"];
        }
        return $nowurl;
    }
}
$n1= new abc();
echo $n1->TagGetCurUrl();
?>
