[eluser]Jonathon Hill[/eluser]

Code:

function current_url($unset = array()) {
        $get = array_diff_key($_GET, (array) $unset);
        $url =
            (($_SERVER['HTTPS'] == 'on')? 'https://' : 'http://').
            $_SERVER['SERVER_NAME'].
            $_SERVER['REQUEST_URI'].
            ((count($_GET) > 0)? '?'.http_build_query($get) : '');
        return $url;
    }
