PHP and Flash Problem

I have a flash application which contains a “dynamic text” with a var name “myVar” and an instance name “dt_txt”
I have a button to which I attached the code:


on (release) {
var lv = new LoadVars();
lv.load (“http://localhost/test.php”);
lv.onLoad = function( ){
_root.dt_txt.text = lv ;
trace(“variables loaded”);
}
}


The “test.php” file contains the simple code:


<?php
$x = “abc”;
print “myVar=$x”;
?>


When I run the flash application (expecting “abc” to show up), I get the following :
myVar=abc&onLoad=%5Btype%20Function%5D
What is wrong?
