title: Get facebook permission for birthday PHP SDK
body: <p>I am trying to get the users birthday from Facebook by the PHP SDK.
  The weird thing is that we have a similar app with similar code and here it displays just fine. In this app it doens't work unfortunately.</p>
  
  <p>This is facebookCon.php (changed appID and secretID):</p>
  
  <pre><code>&lt;?php
  // Remember to copy files from the SDK's src/ directory to a
  // directory in your application on the server, such as php-sdk/
  require_once('facebookPhpSdk/facebook.php');
  
  $config = array(
      'appId'  =&gt; 'MY_ID',
      'secret' =&gt; 'MY_SECRET',
      'allowSignedRequest' =&gt; false // optional but should be set to false for non-canvas apps
  );
  
  $facebook = new Facebook($config);
  $uid = $facebook-&gt;getUser();
  
  // Login or logout url will be needed depending on current user state.
  
  if (!$uid) {
      $statusUrl = $facebook-&gt;getLoginStatusUrl();
      $loginUrl = $facebook-&gt;getLoginUrl(array('scope' =&gt; 'email','user_about_me','user_birthday','user_location'));
  }else{
      $user = $facebook-&gt;api('/me');
      $accessToken = $facebook-&gt;getAccessToken();
      $logged = true;
  }
  ?&gt;
  </code></pre>
  
  <p>and this is the page where I would like to display the birthday:</p>
  
  <pre><code>&lt;?php   
  $user = $facebook-&gt;api('/me');
  echo $user['email'];
  ?&gt;
  </code></pre>
  
  <p>I can retrieve email, first name, last name, locale etc. but not the birthday.</p>
  
  <p>What did I do wrong?</p>
