title: Determining Smartphone / Non-Smartphone for php
body: <p>It seems like facebook has this mastered, I've checked a bit into WURFL but this seems like an extremely expensive process.  I've also checked out: <a href="http://mobiforge.com/developing/story/lightweight-device-detection-php" rel="nofollow noreferrer">url</a> link. While it has a good list of user agents, I'm trying to identify which are smart phones and which are not.</p>
  
  <p>facebook pushes the non-smart phones to a different site than their smart phones. Trying to see if there was an easy way to do this.</p>
