title: Facebook App: Getting a user's name from ID
body: <p>I just had a FB app project turned over to me, and I'm trying to clean up a few items before it goes live.</p>
  
  <p>The original programmer has the user ID number stored in the database, but doesn't display it or the name.  I'd like to display the user's name under the picture they upload.</p>
  
  <p>My code is <code>&lt;?php echo $row['user_id']; ?&gt;</code>, is there a simple way to convert that into the user's name?</p>
