So im new to the PHP world because I have to learn it for work. So one of my clients is a musician and wanted a music player so I made a simple way the user could click a link and load a song.

[PHP]<?php
$song = $_GET['song'];
echo '<a href="/jacobsite/music.php?song=Shpadoinkle.mp3">Shpadoinkle</a><br/>';
echo '<a href="/jacobsite/music.php?song=Dani_California.mp3">Dani California</a><br/>';

echo '<embed qtsrc='.$song.' height"256" width="320" src='.$song.' type="image/x-quicktime" pluginspage="[http://www.apple.com/quicktime/download/]" autoplay="true">';
?>[/PHP]

ok first I set the variable that would change inside the player which I made "$song" and the variable is retreiving the song information from the url. Then in the urls you can see I set the attribute song equal to the mp3 file I want to load.
So now the page loads and when you click a link it gets the $song data from the url. The next step is to insert it into the player where the source was I put in the variable $song. And now your users can click the links and load what ever song they like. I know it is very basic but it gives the user more control over the quicktime player that you would normally need to use a flash player for.
