PHP: reading data posted from flash

1

I have a simple script called display.php:

<?php
echo ‘<pre>’;
print_r($_POST);
echo ‘</pre>’;
?>

It is supposed to display the data posted from flash. Works with other (HTML) forms

Inside Flash, I have some xml data (xmlData) I want to post

 var xmlVars = new LoadVars(); 
xmlVars.xml_data = xmlData.toString;
xmlVars.contentType = "text/xml";
xmlVars.send("display.php", "_blank", "POST");

Note that I have an ISP that does not have the newest version of PHP, so I can’t use the fancy php://input for reading the data.

But isn’t the php script supposed to work?

plz help !
