title: How to properly extract get variables
body: <p>I am still somewhat new to php and was wondering the best way to extract a <code>$_GET</code> variable from a url.</p>
  
  <p>for example how would I capture it out of something like this:</p>
  
  <pre><code>http://www.blahblahblah.com/reset_password.php?token=3072420e7e32cbcf304da791537d757342cf5957
  </code></pre>
  
  <p>just want to get everything from the "<code>token=etc</code>..."</p>
  
  <p>thanks in advance</p>
