Facebook连接 - 注销+销毁会话

Question

I need to get an anchor tag to delete a session in php + log the user out of Facebook. Before I used Facebook connect, I was using this php code to destroy the session:

    if(isset($_GET['logoff'])){
    $_SESSION = array();

 session_destroy();

 header("Location: /");
 exit;
}

And this for the anchor tag:

<a href='?logoff'>Log Out</a>

I now need the same anchor tag to go to the $logoutUrl + destroy the session.

Answer 1

I could be wrong but I am pretty sure Facebook saves the access token in a cookie called fbs_YOURAPPID. So just destroy that cookie and you should sign-out.
