title: Is it possible to pass a php file to html5 audio src attribute?
body: <p>In my php code I have an audio tag with:</p>
  
  <pre><code>'&lt;audio src="song.php" /&gt;'.$fallback.'&lt;/audio&gt;'
  </code></pre>
  
  <p>In "song.php" I tried different things, but nothing worked:</p>
  
  <pre><code>include "thesong.mp3";
  readfile("thesong.mp3");
  echo "thesong.mp3";
  </code></pre>
  
  <p>Is this possible at all?</p>
