Code not work?

[j796160836]

I try to unstandand your code and write a sample on it.

On client-side (Windows phone 8), I use this sample code to generate the Uri.

On server-side, I wrote this sample.
Can you help me to figure out what step I doing wrong?

<?php
require_once("wpn.php");

$sid="ms-app://s-1-15-2-xxxxxxxxxx-xxxxxxxxxx-xxxxxxxxxx-xxxxxxxxxx-xxxxxxxxxx-xxxxxxxxxx-xxxxxxxxxx";
$secret="xxxxxxxxxxxxx-xxxxxxxxxxxxx";

$uri="http://am3.notify.live.net/throttledthirdparty/01.00/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

$wpn = new WPN($sid, $secret);

$xml_data=$wpn->build_tile_xml("hello", "Green.png");

$response=$wpn->post_tile($uri, $xml_data);

var_dump($response);

Works for me
