title: facebook connect uid mysql storage problem
body: <p>I'm doing a facebook connect integration. I use the facebook php library to get the uid,like</p>
  
  <p>$facebook = new Facebook($api_key, $secret);
  $fb_user = $facebook->require_login();</p>
  
  <p>$fbuser is a 16-character long bigint, such as 1000002949493949</p>
  
  <p>However, when I insert this value into mysql it only inserts 2949493949</p>
  
  <p>So later when I try to match uid to the one stored in my database 1000002949493949 it doesn't match because the database is returning 2949493949</p>
  
  <p>The uid field in my database is a bigint with a length of 20. It was originally an int, but I altered it when I started encountering the new, longer uids. </p>
  
  <p>Any idea what I need to do to store the uid correctly?</p>
