Try also
* INI_Get('session.cookie_lifetime')
* INI_Get('session.cookie_path')
* INI_Get('session.cookie_domain')
* INI_Get('session.cookie_secure')
* INI_Get('session.cookie_httponly')
separately instead of session_Get_Cookie_Params().

Additionally there is a "bug" - session.cookie_lifetime is mentioned twice in the description.

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.
