如何使用PHP获取当前URL的前3个部分.

例如:

我的网址:http://something.com/somebody/somegirls/whatever/

获得零件后的结果:http://something.com/somebody/somegirls/

这是我的代码PHP获取当前URL:

<?php   function curPageURL() {
        $url  = isset( $_SERVER['HTTPS'] ) && 'on' === $_SERVER['HTTPS'] ? 'https' : 'http';
        $url .= '://' . $_SERVER['SERVER_NAME'];
        $url .= in_array( $_SERVER['SERVER_PORT'], array('80', '443') ) ? '' : ':' . $_SERVER['SERVER_PORT'];
        $url .= $_SERVER['REQUEST_URI'];
        return $url;
    }

 $current_url = str_replace("www.", "", curPageURL());

?>
