HELP! need php variables in flash

The action script below loads two videos ( first.flv, second.flv) then plays them consecutively. I would like to load the videos as variables from a PHP page that this flash is embeded in - something like:

$first_flv = "first.flv";
$second_flv = "second.flv";

How can I get $first_flv and $second_flv into flash variables that can replace the hard-coded ( "first.flv", "second.flv") below?


//action script

var videoLoaderIndex:Number = 0;
var videoPlayerIndex:Number = 0;
var videoList:Array = new Array( "first.flv", "second.flv");

vidComp.contentPath = videoList[0];

function eready(e:Object):Void {
if( videoLoaderIndex < videoList.length ) {
videoLoaderIndex++;
vidComp.activeVideoPlayerIndex = videoLoaderIndex;
vidComp.load( videoList[videoLoaderIndex] );
}
}

vidComp.addEventListener("ready", eready);
function ecomplete(e:Object):Void {
++videoPlayerIndex;
if(videoPlayerIndex >= videoList.length) {
videoPlayerIndex = 0;
}

vidComp.activeVideoPlayerIndex = videoPlayerIndex;
vidComp.visibleVideoPlayerIndex = videoPlayerIndex;
vidComp.play();
}

vidComp.addEventListener("complete", ecomplete );
