Passing variable from php into flash, help please

Question

Here are what I'm having:
<?PHP
$testVal = "This is a test";
$test = urlencode($testVal);
$out = "test=". $testVal;
echo $out;
?>
// and this is my flash file
function getData() {
// Prepare request
var urlReq:URLRequest=new URLRequest("http://localhost/test.php");
urlReq.method=URLRequestMethod.GET;
var loader:URLLoader = new URLLoader();
loader.dataFormat=URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE, completeHandler);
loader.load(urlReq);
function completeHandler(evt:Event) {
var vars:URLVariables = URLVariables(evt.target.data);
trace(" TEST = ", vars.test);
trace(" TEST = ", unescape(vars.toString()));
// and below is the ouput
TEST = undefined
TEST = test=This is a test
I've tried with several different ways to get ONLY the value of the variable - that means I only want to have "This is a test" returned, but I either got "undefined" or the whole thing "test=This is a test", instead.
I'm new to Flash and PHP. Please help.
Thanks

There's no need to write any fake variables out, Flash does not need that. OK, here's a simple PHP script like yours - I called it test.php
<?PHP
     $testVal = "This is a test";
     $out = "test=". $testVal;
     echo $out;
?>
And the AS to call it:
var myLoader:URLLoader = new URLLoader();
myLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
myLoader.load(new URLRequest("http://www.mydomain.com/test.php"));
myLoader.addEventListener(Event.COMPLETE, dataLoaded, false, 0, true);
function dataLoaded(e:Event){  
    trace( e.target.data.test);
You will see 'This is a test' traced to the output window.
