如何解析facebook图形对象并在视图中迭代？

Question

I am trying to parse the facebook graph object and allow the view to iterate through the objects and its array. However, I am hitting a roadblock and the view is showing blank.

facebook library:

require_once('Facebook/autoload.php');

use Facebook\FacebookSession;
use Facebook\FacebookRequest;
use Facebook\GraphUser;
use Facebook\FacebookRequestException;
use Facebook\FacebookRedirectLoginHelper;

class Facebook {
  protected $ci;

  public function __construct() {
    $this->ci =& get_instance();
    $this->ci->load->library('session');
    if(!isset($_SESSION)) {
      session_start();
    }
    FacebookSession::setDefaultApplication($this->ci->config->item('api_id', 'facebook'), $this->ci->config->item('app_secret', 'facebook'));
    $this->session = new FacebookSession($this->ci->config->item('app_token', 'facebook'));
  }

  public function get_user_profile($user) {
    $request = (new FacebookRequest($this->session, 'GET', '/' . $user))->execute()->getGraphObject(GraphUser::className());

    return $request;
  }
}

controller:

$data['facebook'] = $this->facebook->get_user_profile("coach");
$this->load->template('default_template', $data);

view:

foreach($facebook as $fb_item) {
  echo var_dump($fb_item);
  echo var_dump($facebook);
}

But what I really want to do is:

echo $fb_item->name; //to return name if its singular
echo $fb_item->cover->id; //for the multi dimensional objects
echo $fb_item->cover->source;

the object that is returned when doing a print_r:

)

Any tips or direction on how to proceed?

Answer 1

Ok I was able to figure out the solution. Return the object as an Array:

getGraphObject()->AsArray();

Then you can iterate through via the View.
