I am trying to integrate facebook for my canvas app. When i run app from facebook with following code // init app with app id (APPID) and secret (SECRET) FacebookSession::setDefaultApplication('xx','xx'); $helper = new FacebookCanvasLoginHelper(); try { $data = array('oauth_token' => 'token'); $data['algorithm'] = 'HMAC-SHA256'; $data['issued_at'] = time(); $base64data = base64_encode(json_encode($data)); $rawSig = hash_hmac('sha256', $base64data, 'app_Secret', true); $sig = base64_encode($rawSig); $signedRequest = $sig.'.'.$base64data; $_GET['signed_request'] = $signedRequest; $session =

This is for a canvas app on the Facebook Platform using the new(est) Facebook PHP SDK. We are using the PHP example from the Facebook tutorial (https://developers.facebook.com/docs/appsonfacebook/tutorial/) to trigger the OAuth dialog and get the test user to the redirect URL.

I have tried the PHP SDK (v.3.1.1), and the current Javascript SDK as suggested here : https://developers.facebook.com/docs/guides/web/ now when trying to log out I have tried both FB.logout() ( for js ) and $facebook->getLogoutUrl() ; as the documentation for both clearly state, these methods log the user out of the application as well as their facebook session. But I only need to log the user out of the facebook application ( the test site ). I have tried logging the user out of my test site, ignoring the facebook aspect. But in this case, when the user clicks the login button again, the
