How to create remember me session cookie in Symfony2

session.php

<?php
require __DIR__ . '/vendor/autoload.php';

use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\HttpFoundation\Session\Storage\NativeSessionStorage;
use Symfony\Component\HttpFoundation\Session\Attribute\NamespacedAttributeBag;

$options = array(
    'cookie_lifetime' => 123456,
    'cookie_httponly' => true,
);
$session = new Session(new NativeSessionStorage($options), new NamespacedAttributeBag());
$session->start();

if ($session->get('name')) {
    echo " World ! " . $session->get('name') . " <br /> ";
    echo " Hello " . $session->get('next');
} else {
    // set and get session attributes
    $session->set('name', 'Drak');
    $session->set('another', 'Boom');
    $session->set('next', 'Next');
}

So session life time is for all the session names, not just for one session. I thought in ZF2 session they are only storing the session lifetime for specific session. But I am wrong.
