title: Making a URL shorter - PHP get
body: <p>How can I access a variable GET variable from PHP if the URL is like this:
  <a href="http://example.com/somehash" rel="nofollow">http://example.com/somehash</a></p>
  
  <p>I obviously know how to do it when there is something like this:
  <a href="http://example.com/f.php?h=somehash" rel="nofollow">http://example.com/f.php?h=somehash</a></p>
  
  <p>Here I would just take $_GET["h"], but i don't know how to do it for the first case...</p>
