PHP sessions destroy across sub domains

This could be the sequel of this question: PHP Sessions across sub domains

I have a successful multi-domain session simply using this:

session_set_cookie_params(0, '/', '.domain.com');
session_start();

The problem is when I try to logout from domain.com. I have tried everything for logout, even all this, as suggested in PHP session_destroy() manual:

// 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"]
  );
}

But it's not working. The session is still alive when I visit subdomain.domain.com.

How can i do it?

Thank you!

Did you see if the session is started before you try to destroy it? 

if (!isset($_SESSION)) session_start();
if (isset($_COOKIE['auth_token'])) {
remove_token($_COOKIE['auth_token']);
setcookie("auth_token", "", time()-3600, "/", ".domain.com");
}
session_destroy();

This is working code from my environment. Hope it helps.
