Cookie headers are only sent as soon as the user laods a new page. So just unsetting the browser server side will not delete it on the client.

Also be aware of the domain. You should always use a fourth parameter to set a cookie for all paths on your site. If you don't do that, a cookie from a subfolder might still exists.

You can check with cookies are set using some JavaScript function or the Web Developer Toolbar for Firefox.

Properly destroy the session and set the session cookie var to expire in the past.

From the PHP.net manual on session destroy:

    <?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();
?>
