Store objects in sessions Symfony 2

Question

I am writing a small e-shop application with Symfony 2 and I need some way to store the user\'s shopping cart in a session. I think using a database is not a good idea.

Don't know if this way is the better way to store your data temporary. You can use this to instantiate a session object :

$session = $this->get("session");

Don't forget the 'use' in your controller :

use Symfony\Component\HttpFoundation\Session;

Then, the session starts automatically when you want to set a variable like :

$session->set("product name","computer");

This is based on the use of the Session class, easy to understand. Commonly definitions :

get(string $name, mixed $default = null)

Returns an attribute.

set(string $name, mixed $value)

Sets an attribute.

has(string $name)

Checks if an attribute is defined.
