using $_SESSION['fb_'.APP_ID.'_user_id']

Question

I'm developing a fb application with php sdk 3.0 and I've noticed that Facebook starts a session that contain the app_ID like that: $_SESSION['fb_'.APP_ID.'_user_id']; This session store the facebook uid of the connected user. Is this a feature of PHP SDK or is not recommended to work with this session?

To explain: After login successfully to my fb app, I use this function to see the php sessions print_r($SESSION); and there is a session $_SESSION['fb_173620963485_user_id'] = 123456;WHERE 173620963485 is my appID and 123456 is my fb uid.

Is recommended to work with this session: $_SESSION['fb_173620963485_user_id'] ?

I do not understand the question.

You don't use this session for anything. Period.

You should never need to touch the $_SESSION['fb_..._user_id'] variable. Use the SDK like the documentation states and you will be much better off. If you want access to the user ID, just use:

$uid = $facebook->getUser();

Take the time and read the documentation, and that should help.
