How to send flash values to php?

my code is:

var lvReceive = new LoadVars();
var mcLoaderThree:MovieClipLoader = new MovieClipLoader();
mcLoaderThree.addListener(this);
for (var i = 1; i<=9; i++) {
var containerThree:MovieClip = createEmptyMovieClip(“containerThree”+i, i);
containerThree._name = “s”+i;
mcLoaderThree.loadClip(“http://sumanth/test/flash/cards/cardsgif/s"+i+".gif”, containerThree);
containerThree._x = 20*i;
containerThree._y = 10;
}
function onLoadInit(mc:MovieClip) {
mc.onPress=function()
{
this.startDrag();
xstart = this._x;
ystart = this._y;
}
mc.onRelease=function()
{
this.stopDrag();
var imgname = this._name;
//trace(imgname);
xstart = this._x;
ystart = this._y;
lvReceive.loadVariables(“http://sumanth/test/flash/ftop.php”, “”, “_POST”)
}
}

ftop.php is:

<?php
$imgname = $_POST[‘imgname’];
echo $imgname;
?>

when i execute http://sumanth/test/flash/ftop.php nothing is displaying why?
i also checked with
lvReceive.SendAndLoad(“http://sumanth/test/flash/ftop.php”, lvReceive,“POST”);
but no use
plz give me the solution thanks in advance…
