PHP Variables Not Loading?

Heres a basic script I found, of course not flash 8 formatted to look shiny but:

phpfilepath = "http://freish.freehostia.com/files.php";
myVars = new LoadVars();
myVars.load(phpfilepath);
myVars.onLoad = function() {
	total.text = this.x;
};

In the php file:

<?php

$x = "abc";
print $x;

?>

Any reason why flash doesnt load “abc” into total.text? My php file permissions are set to 755 by default.
