Max CDN purge through API - php

Question

I am trying to purge a file through the MaxCDN API but it's not working. Here's the code I'm using. The print_r doesn't return any result.
function purge() {
date_default_timezone_set('America/Los_Angeles');
$date = date('c');
$apiid = 'myapiid';
$apikey = 'myapi';
$auth_key = hash('sha256', $date.':'.$apikey.':purge');
$url = 'http://softsailor.alexdumitru.netdna-cdn.com/wp-content/themes/ss3/includes/sprite.jpg';
if (!class_exists('IXR_Client')) {
require_once (ABSPATH . WPINC . '/class-IXR.php');
}
$client = new IXR_Client('api.netdna.com','/xmlrpc/cache',80);
$client->timeout = 30;
$client->query('cache.purge', $apiid, $auth_string, $date, $url);
print_r($client->getResponse());
}
I turned debug on and I'm getting the following error
Something went wrong - -32300 : transport error - HTTP status code was not 200

Hey Alex. I work at MaxCDN and here is a code example that I took from our Wiki:
<?php
date_default_timezone_set('America/Los_Angeles');
include("lib/xmlrpc.inc");
$cur = date('c');
$apiKey = 'api-key';
$apiUserId = 'api-user-id';
$namespace = 'cache';
$method = 'purge';
$authString = hash('sha256', $cur . ':' . $apiKey . ':' . $method);
// this is the url to purge
$url= 'http://static.jdorfman.netdna-cdn.com/static/images/frugal-it-logo.png';
$f=new xmlrpcmsg("$namespace.$method", array(php_xmlrpc_encode($apiUserId),
php_xmlrpc_encode($authString), php_xmlrpc_encode($cur),
php_xmlrpc_encode($url)));
$c=new xmlrpc_client("/xmlrpc/cache", "api.netdna.com", 80,'http11');
$r=&$c->send($f);
print_r($r);
?>

jdorfman's example dumps the entire raw response but if you are like me you want to get it into data objects using php
Here are some helpful tips:
$r->serialize() to access just the raw XML response
to convert to JSON use this:
$xml = simplexml_load_string($r->serialize());
echo json_encode($xml);
