This function is quite handy when it comes to expiring session cookies... since Session cookies don't automatically get destroyed (see the session_destroy page).



For instance, here's what I plan to use to expire session cookies:



    $CookieInfo = session_get_cookie_params();

    if ( (empty($CookieInfo['domain'])) && (empty($CookieInfo['secure'])) ) {

        setcookie(session_name(), '', time()-3600, $CookieInfo['path']);

    } elseif (empty($CookieInfo['secure'])) {

        setcookie(session_name(), '', time()-3600, $CookieInfo['path'], $CookieInfo['domain']);

    } else {

        setcookie(session_name(), '', time()-3600, $CookieInfo['path'], $CookieInfo['domain'], $CookieInfo['secure']);

    }

    session_destroy();



It doesn't check to see if the path part of the session cookie is set because the defaults in php.ini have this set already, unlike domain and secure.
