php - Log out facebook when user doesn't give permission -

my app (facebook-php) uploads images user's wall, , page. works fine, logging out after uploading.

there problem when user logs in email , pw, , presses cancel when asked permission birthday etc. moment, user logged in, can't make valid logout link

$params = array( 'next' => 'http://localhost/index.php' ); $facebook->getlogouturl($params); 

(access_token "0").

the way logout go facebook.com , click logout. there way can logout user?

no, user decides when logged out or logged in on facebook, cannot decide him on issue or add such button.

you need adapt application handle case instead, cannot log out user, can know if user logged in or not, , display application accordingly.
