title: adding custom variables to Twilio action urls / $_REQUEST variables using PHP
body: <p>I did see this thread:  <a href="https://stackoverflow.com/questions/19121392/is-it-possible-to-add-additional-variables-to-the-action-attribute-in-the-gather">Is it possible to add additional variables to the action attribute in the gather tag?</a></p>
  
  <p>and that would work, but that would mean I have to set up my directory for mod-rewrite, and I was hoping for something a little more direct and simple.</p>
  
  <p>Is there a way to append custom variables to Twilio PHP action urls ($_REQUEST variable) without literally writing them out?  When I add them manually it creates parse errors.  </p>
  
  <p>I've tried $_REQUEST['my_var'] = $value but it isn't working.</p>
