Disable Flash

Ok ive searched for so long on how to do this i simply want to use the

loadVars();

method to get a variable from a php script or even a .txt file… the thing is ive done this once before but i was using an actual php file hosted on some other server that was ALOT more than

<?php
$On = "On";
?>

im trying to do this so incase i want to turn off my flash (just delete or edit the php script from my private host so it would then not get the info and go to a blank frame)

ill give you my flash code here

    stop();
    On = new LoadVars();
    On.sendAndLoad("URL rather not give it out" + getTimer(), On, "POST");
    On.onLoad = function(success) {
        if (success) {
            gotoAndStop(2);
        } else {
            gotoAndStop(1);
        }
    }

please help me quickly
