php - getting current URL

Question

I am using following code to get the current URL

$current_url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

Is there any other way to get the same, or may be better way to get current URL?

Thanks.

From the reference:

<?php

function curPageURL() {
    $pageURL = 'http';

    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;
}
?>
