How Facebook Graph API Access Objects (2)

In previous post,  I got the basic user information of the App user with the this line of codes:

$user = $facebook->api('/me');

required information, as illustrated with the diagram below:

Similarly we can get the friends of user in the same way with the following codes:

<?php
      $userFriends = $facebook->api('/me/friends');
      print_r($userFriends);
?>

The calling to the api() function can also be illustrated with the diagram below:

Now we have some basic idea how to make a call to the api() function of the facebook class, we can do more interesting thing with the App.
