title: How can I play multiple files in an AGI script?
body: <p>I am able to stream multiple files together using:</p>
  
  <pre><code>$AGI-&gt;exec('Background',"file1&amp;file2&amp;file3&amp;file4")
  </code></pre>
  
  <p>However, this doesn't return the key pressed by the user when the files are being played. So, I used <code>$AGI-&gt;stream_file</code>, which returns the key pressed, but only plays a single file.</p>
  
  <p>I need to be able to play multiple files together, the playback should stop the moment a key is pressed by the user, and I should know which key was pressed.</p>
  
  <p>How do I achieve this?</p>
