The get_url() function below a bit smaller and a slight bit improved, yet much uglier.

<?php

function get_url($show_port = false)
{
    $protocol = ($_SERVER['HTTPS']) ? 'https://' : 'http://';
    $host = $_SERVER['HTTP_HOST'];
    $port = ($show_port || $_SERVER['SERVER_PORT']!=80) ? ":{$_SERVER['SERVER_PORT']}" : '';
    $file = $_SERVER['SCRIPT_NAME'];
    $query = ($_SERVER['QUERY_STRING']) ? "?{$_SERVER['QUERY_STRING']}";
    return $protocol.$host.$port.$file.$query;
}
