title: Get Facebook `userid` or `username`
body: <p>Is there an easy way to get the user's facebook userid and/or username via php that is recent.  I'm beat.  I'll do more research tomorrow; I've now spent over a week looking over APIs and outdated docs.  I'm using the Graph API....just wondering if anyone has a shortcut, once the user proceeds from my website, logs into FB, then accepts the permission for my App.</p>
  
  <p>I know there's a lot of bouncing back and forth with the authentication and token thing.  I can retrieve everything but the user's id.  I can even get to a final page on MY website where you enter your FB name and can make the post.  I just can't figure out the user name/ ID automatically.</p>
  
  <p>I've looked in the $_SESSION, $_COOKIE, $_POST and $_GET superglobals.</p>
  
  <p>I know it's something easy I'm overlooking.  I'm willing to give the url out...heck I'll even create a login on my server if you want to search the PHP code.</p>
