Ok, really lost now

alright, i posted a question in another forum about populating xml from mysql using php. i got 2 responses: " i think so" and “i don’t know”…
i found this forum and i had it solved in less than 10 minutes. awesome.
now…
the reason i was looking for a script to do this:
i have a swf mp3 player that uses an xml playlist but i wanted to use it on my site with the mp3s i’ve upload into mysql database.
like i said, i have the xml output from php working no prob. but how do i direct it to the swf player? the player needs to be directed to an xml file in the <embed src> to get the playlist.
in short, how would i make the swf player think the php file (output xml) is really an xml file and load the playlist?
any help would be greatly appreciated,
thanks in advance.
