To keep session values with Symfony sessions, you can use the built-in session handling mechanism provided by Symfony. Here's how you can store and retrieve session values in Symfony:

1. Storing a value in the session:

1

$session = $this->get('session');
$session->set('key', 'value');

1. Retrieving a value from the session:

1
2

$session = $this->get('session');
$value = $session->get('key');

1. Checking if a session key exists:

1
2
3
4

$session = $this->get('session');
if ($session->has('key')) {
    // Key exists in session
}

1. Removing a value from the session:

1
2

$session = $this->get('session');
$session->remove('key');

By using these methods, you can easily store and retrieve values in the session in Symfony. Remember that session values are stored on the server-side, so they can be accessed across different requests within the same session.
