title: Using the Graph API does not get notifications (PHP SDK)
body: <p>I have followed the instructions to get access_token and use the graph API to get notifications. My PHP code is like: </p>
  
  <pre><code>echo "get limit 3 notifications";
  
  $args = array(
   'limit' =&gt; '3',
   'access_token' =&gt; 'mytoken....'
   );
  
   $data = $facebook-&gt;api('/my_facebook_id/notifications','GET',$args);
  
   $arrays = $data['data'];
  
   echo "count size: ".count($arrays).;
  
   print_r($arrays);
  
   echo "&lt;br/&gt;&lt;br/&gt;";
  </code></pre>
  
  <p>However, I always get zero notifications. Although, when I logged in, there is two new notifications in my home page. </p>
  
  <p>Has anyone encountered such a problem? </p>
  
  <p>Also, I want to get messages using the graph API but seems there is no 
  "http://graph.facebook.com/my_facebook_id/messages/" </p>
  
  <p>Regarding to the notifications and messages, they are all in the top left bar, following friends requests. </p>
  
  <p>I wonder if someone has experienced with this and can help.</p>
