Add flashvars in AS2 Code

hi all

I m passing variable/ file name in html/ php like this


<PARAM NAME=FlashVars VALUE="flashvars=all_that.mp3"> 

I m NOT using playback component. so i cannot write


player.contentPath = flashvars

I m creating custom player and want to use flashvars in AS2 in my file and call it dynamically in PHP.

this is how i m calling the mp3 file


SD = new Sound();
SD.loadSound("all_that.mp3", true);

How can i pass flashvars in actionscript.

or is their anyother solution or alternative that i can use.
