For example, can I use the following method to get any user’s friends? what should the access_token field be?
$friends = json_decode(file_get_contents('https://graph.facebook.com/user_id/friends?access_token=...'),true);
Is it possible to create a php page that when we only input a user’s id or name without logging into the user’s account, it returns all his/her friends’ profile pictures automatically?
Thanks!

A: you gain it when you login to facebook using graph api – it is related to the user and the application (AppID) specified during login.
