title: unable to fetch data from close group using Facebook graph api
body: <p>I am unable to fetch closed group posts from facebook.
  As I'm the member of that group but i cant access it via my access token in graph api. But I can fetch all the data from open groups with my access token 
  in which i am a member.</p>
  
  <p>I am using this url:
  [<a href="https://graph.facebook.com/my-group-id/feed?access_token=my-access-token]" rel="nofollow">https://graph.facebook.com/my-group-id/feed?access_token=my-access-token]</a></p>
  
  <p>My Code:</p>
  
  <pre><code>&lt;?php
     $group = array(
      array('id'=&gt;'xxxx','name'=&gt;'zzzzz'),
      array('id'=&gt;'xxx' , 'name'=&gt;'yyyy'),
      );
  
    $access_token = 'my token';
  
    $n = count($group);
    $i = -1;
  
    while($n--){
          $i++;
          $add = 'https://graph.facebook.com/'.$group[$i]['id'].'/feed?fields=id,name,story,message,updated_time&amp;access_token='.$access_token;
          $json = file_get_contents($add);
          $data = json_decode($json);
          if($json){
              foreach($data-&gt;data as $item){
                $post_id = $item-&gt;id;
                $name = $item-&gt;name;
                $date = $item-&gt;updated_time;
                $story = $item-&gt;story;
                $message = $item-&gt;message;
              }
          }
    }
  ?&gt;
  </code></pre>
