Get URL without base URL

With this code, a [geturl] shortcode will be created. This shortcode shows the current page full URL address:

add_shortcode ('geturl', 'get_current_page_url');
function get_current_page_url() {
    $pageURL = 'http';
    if( isset($_SERVER["HTTPS"]) ) {
        if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
    }
    $pageURL .= "://";
    if ($_SERVER["SERVER_PORT"] != "80") {
        $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
    } else {
        $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
    }
    return $pageURL;
}

My problem is that it contains the base url. Example, i have one test1 folder and there is one another page (test2): www.test.com/test1/test2 On this page, the shortcode will show this: www.test.com/test1/test2 But I want to remove the base url: and the code should only show the parts after the baseurl. So what I want the code to show is: /test1/test2

Is it possible?
