symfony Doctrine database session storage
Sessions are normally managed by your server and depending upon how involved you get with the PHP setup you need never know how this data is stored. The default setup for PHP is to store session data in temporary files on the server. So why would we want to change how sessions are handled and what advantage can we gain from any changes we make.
Why use database session management?
Sessions allow you maintain persistence within PHP applications. With every HTTP request a PHP application must re-assign every variable and object needed in your application. Sessions allow you to store data that is required to persist past each HTTP request allowing it to be easily retrieved and used.
