Symfony 2 and user session variables from an inherited application

Question

I am trying to configure migration from Legacy code to Symfony, and I am trying to use legacy session variables between two applications.

Now I can var_dump($_SESSION)in app_dev.php, and the key user_idis from an outdated application. However, when I run the following in the controller, I do not get any session variables:

var_dump($request->getSession()->all());

To clarify , I currently have access to $_SESSION['user_id'], so the session is distributed among applications successfully, but the Symfony session object and parameter packages do not contain expired keys.

My goal:

• For the key user_idthat will be available in the call$request->getSession()
• For all other keys that will be available here.

My problems:

PHP Session bridge, , , . Symfony, , , - , Symfony.

Symfony , , "Bags", $_SESSION. , Symfony $_SESSION, , $_SESSION . [ ]

TheodoEvolutionSessionBundle, , Symfony 3.

, Symfony $_SESSION['_sf2_attributes'], , app_dev.php:

$_SESSION['_sf2_attributes']['user_id'] = $_SESSION['user_id'];

, session_start().

$_SESSION Symfony Session? - Symfony, ? , $_SESSION['_sf2_attributes'] "" , ?

kernel.request, Symfony one:

if (isset($_SESSION['user_id'])) {
    $event->getRequest()->getSession()->set('user_id', $_SESSION['user_id']);
}
