  7. hello how i can use user_photos in api this is my code $user_fre = $facebook->api(‘/me/photos?limit=2&type=uploaded’);

    1. To fetch email address you must have the permission to access it. To request permissions, add email to the scope as shown below –

      $facebook->getLoginUrl(array(‘scope’ => ’email,read_stream’));

      1. Hi I’ve tried that but it comes with an FB error:
        Invalid Scopes: read_stream. This message is only shown to developers. Users of your app will ignore these permissions if present.
