Im assuming flash wont let you do this because it is not on the same host, right?
In action script do this
loadVariables("http://www.yourdomain.com/thephpscript.php?name=drew&id=100", "GET");
Then in thephpscript.php,
<?php
$request = "GET /test.asp?name=".$_GET['name']."&id=".$_GET['id']." HTTP/1.0\r\n".
"Host: www.test.com\r\n".
"\r\n";
$fp = fsockopen ("www.test.com", 80);
fputs ($fp, $request);
while (!feof($fp))
{ echo fgets ($fp,128);
}
fclose ($fp);
?>
you might be able to use javascript in flash as a workaround
