title: Knowing with PHP if the browser can play audio file with html5 audio tag
body: <p>My question might be weird, but I don't know how to phrase it…</p>
  
  <p>Actually, I would like to know whether or not the user's browser support mp3, ogg and wav files (I want the information for each).
  I know, I could just make the distinction between firefox and safari/chrome for a start, but there are several browsers I wouldn't take into consideraton.</p>
  
  <p>How could I proceed ?</p>
  
  <p>Thanks !</p>
