Yes it is. When you have implemented the library into your CodeIgniter application, use the following to get an array of your friends user IDs in the home.php controller:
$friends = $this->facebook_connect->client->friends_get($data['user_id']);
This will return an array of IDs. Then use users.getInfo I believe to return information on each user, though I haven't used this yet.
