Symfony 2 gets a list of registered users

Question

I am writing some applications in symfony 2. I need to get a list of users who are logged in to the application.

Answer 1

You can...

• Grab the "onRequest" event and save the user_id timestamp in your database for the last time this happened. (this is updated every time a user clicks a link on your site).

• Have your users send heartbeats via AJAX to your server (easily with jQuery) and save the user_id timestamp in your database for the last time this happened. (this is updated at known intervals)

• Grab the onSecurityInteractiveLogin event and save the timestamp in your database, delete it when you log out (many users never log out)
