title: Facebook mobile login with PHP SDK
body: <p>I could get Facebook token from Android device and post the value to the web server.</p>
  
  <p>When I used Facebook PHP SDK, it was easy to get facebook user information.</p>
  
  <pre><code>// Get User ID
  $fb_id = $this-&gt;facebook-&gt;getUser();
  
  // Get User Info
  $user_profile = $this-&gt;facebook-&gt;api('/me');
  </code></pre>
  
  <p>Just this one line gave me all the information.</p>
  
  <p>I have no idea how to get a user information by using only facebook token that I get from mobile.</p>
  
  <pre><code>// get mobile token
  $fb_token = $this-&gt;input-&gt;post('fb_token');
  
  $user_info = 'https://graph.facebook.com/me?access_token='.$fb_token;
  </code></pre>
  
  <p>Ok. so It looks like I get joson data if I use above url address.</p>
  
  <p>How can I bring the array data into the server?</p>
