title: VXML Value to PHP Variable
body: <p>I have a single page VXML Script, I have passed dialed DTMF to a form and that works fine.</p>
  
  <p>But I would also like to pass the value into a PHP Variable.</p>
  
  <p>Is that possible ?</p>
  
  <pre><code>&lt;prompt&gt; &lt;value expr="Digits"/&gt; &lt;/prompt&gt;
  </code></pre>
  
  <p>This works but how to I assign 'Digits' to $test in PHP ?</p>
  
  <p>Thanks</p>
