// Why do you create another $session object just to replace the previous one with the exact same fb_token?

// Also, may just be personal preference, but shouldn't you getGraphObject typed as a GraphUser object, considering you are accessing /me? Then you have an object, not an array. For example:

// $me = (new FacebookRequest(
// $session, 'GET', '/me'
// ))->execute()->getGraphObject(GraphUser::className());

// And you really should use Composer, having to manually require 10+ classes is insane. :)
