title: Can I have multiple $_GET with the same key, different values?
body: <p>Is it possible to retrieve the arguments from a url where the same $_GET has different values?</p>
  
  <p>Such as <code>www.domain.com/?user=1&amp;user=2</code></p>
  
  <p>Currently this only shows whatever is listed second, so if I <code>echo $_GET['user']</code>, it would output <code>2</code></p>
  
  <p>I couldn't seem to find this on SO, so if I missed it please let me know.</p>
  
  <p>Thanks for your help!</p>
