$me = null;
// Session based API call.
if ($session) {

  } catch (FacebookApiException $e) {
    error_log($e);

// login or logout url will be needed depending on current user state.
if ($me) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl();
}


if ($session) {
    // We have a valid FB session, so we can use 'me'
 $result = $facebook->api('/me/feed','post',array('message' => 'testmessage'));
} elseif( isset($_SESSION['user_id']) ) {
$result = $facebook->api("/{$_SESSION['user_id']}/feed",'post',array('message' => 'testmessage'));
