Best way to send variables from php to flash?

Hi… can anyone please tell me the best way to load multiple variables from a php flile into flash?? I have been trying with no luck… I’m printing them from the php like this:

print "mx=$movx&my=$movy&bg=$bgC";

and them impor them to flash using this code:

loadRemote.onRelease = function() {
    mData = new LoadVars();
    mData.load("load.php");
    movingX = mData.mx;
    movingY = mData.my ;
    bgColor = mData.bg;
    if (mData.mox != undefined) {
        this.preview(4);
        alert.msg.text = "working!";
    } else {
        alert.msg.text = "load error!!";
    }
};
