Are you using the Symfony 2 framework, or just the Twig component? — frumious, Sep 17 '14 at 08:42

You don't "implement sessions in Twig", period. You implement sessions in PHP code, and then pass any information that you may want to display in your HTML template to Twig to render. E.g.:

session_start();
$_SESSION['count'] ... // do whatever you want here to count

$twig = new Twig_Environment(...);
echo $twig->render('my_template.twig', ['count' => $_SESSION['count']]);

This handles your session code, and then passes the session's count value to Twig. Inside your template, you can then output it:

<p>{{ count }}</p>

You can pass the entire $_SESSION array to Twig, so you have access to everything in it.

I have not used the entirety of Symfony yet, so no. If you need help specifically with that, ask a new question specifically for that. – deceze Sep 17 '14 at 09:47

`var page = {{ count }};` (Or `{{ accesses }}`, or whatever you name the value as when passing it to Twig.) – deceze Sep 17 '14 at 10:51
