title: Obtain or verify owner or admin of a fan page
body: <p>Is there any way to verify that the user owns the fan page or get the id of the owner or admin of the fan page?
  I tried as well but it did not work, I've read a lot but did not find anything.</p>
  
  <pre><code>$facebook = new Facebook(array(
      'appId'=&gt;'', // replace with your value
      'secret'=&gt;'' // replace with your value
  ));
  $signedRequest = $facebook-&gt;getSignedRequest();
  if( $signedRequest['page']['admin'] )
  </code></pre>
