I\'ve got the Facebook user ID of the user who created a given page. Now I need to get the page ID to display like box in my website.
Different users have their own Face
The page id is included in the signed request. Here an updated version of byron's post for facebook's page update.
$facebook = new Facebook();
$signed_request = $facebook->getSignedRequest();
$page_id = $signed_request['page']['id'];
echo 'page id is ' . $page_id . ' AAAAAAAAAAWWWWWWW YYYYYYEEEEEEEEAAAAAAAAAAAA!';
