在浏览器中播放动态声音片段

I've never delt with sound clips and im wanting to play one via an event.

I have a file which has a snippet like so:

if( $get['0002'] == 'mu' ) {
    switch( $get['0000'] ) {
        case 'mp3': header('Content-Type: audio/mp3'); break;
        case 'wav': header('Content-Type: audio/x-wav'); break;
        default: break;
    }
    echo file_get_contents('./folder-name/' . $get['0001'] . '.' . $get['0000'] );
    exit;
}

and on the page I fave this button;

<input type="button" value="Play Sound" onClick="EvalSound('sound1')" >

and this hidden away in the background

<embed src="./?0000=wav&0001=0001&0002=mu" autostart=false width=0 height=0 id="sound1" enablejavascript="true">

and the js being;

<script>
function EvalSound(soundobj) {
  var thissound=document.getElementById(soundobj);
  thissound.Play();
}
</script>

This does not seem to work and I believe it has something to do with the PHP headers. Could someone please point me in the right direction, as it would be much appreciated.

Please do some testing here with: http://www.phon.ucl.ac.uk/home/mark/audio/play.htm

On firefox I get an error for the Play() function.

Use something like firebug to give you more information.

If everything works then start debugging your php script.
