Cannot delete cookies set in JavaScript on the server.

I am trying to write PHP code to delete all user cookies in my domain.

Here is what I got:

<?php
$domain = 'www.example.com';
$deleteExpiration = time() - 60*60*24*365*10; // 10 years ago
foreach (array_keys($_COOKIE) as $cookie) {
    setcookie($cookie, 0, $deleteExpiration, '/', $domain);
}

Running this code at http://www.example.com/delete_cookies.php deletes all cookies set on the server, but not cookies set in JavaScript.

I checked using the Firefox Cookies dialog box in which the cookie problem really is (path = /; domain = www.example.com). Using Live HTTP headers, I see that the following header is being sent:

Set-Cookie: CookieName=0; expires=Fri, 12-Mar-1999 19:36:15 GMT; path=/; domain=www.example.com

Therefore, I believe the setcookie command works as expected. Firefox just does not fulfill the request.
