title: Multiple HTTP GET parameters with the same identifier
body: <p>Let's say I am getting requests such as:</p>
  
  <p><code>http://www.example.com/index.php?id=123&amp;version=3&amp;id=234&amp;version=4</code></p>
  
  <p>Is it possible to extract these in a simple way inside my php code? I realize I could get the entire querystring with javascript using window.location.href and handle it manually but I'm looking for something more elegant. The requests can contain any number of version/id pairs but I can assume that the query is well-formed and have no obligation to handle invalid strings.</p>
