// Make a new request and execute it.
try {
  $response = (new FacebookRequest($session, 'GET', '/me'))->execute();
  $object = $response->getGraphObject();
  echo $object->getProperty('name');
} catch (FacebookRequestException $ex) {
  echo $ex->getMessage();
} catch (\Exception $ex) {

// You can chain methods together and get a strongly typed GraphUser
