PHP Facebook API. How can I tell if my application is active via the API? -

-

does know whether there api call tell me whether application still active? example, have login system users can sign in facebook credentials, wiould periodically check application login uses, still active facebbok side.

any ideas?

check existence of facebook api cookie. in facebook api have facebook.php file manages session , cookies. file shall included @ beginning of every php page uses fb authentication.

locate part :

$session = $facebook->getsession();  $fb_me = null; // session based graph api call if ($session) {   try {     $fb_me = $facebook->api('/me');     $fb_uid = $facebook->getuser();   } catch (facebookapiexception $e) {     d($e);   } }

later in code, check whether fb_me exists, if yes authenticated via fb , can use other variables of api information user.

if( $fb_me ) {   echo "you authenticated via fb api user id:".$fb_uid; }
