// create a new pubsubhubbub publisher
$p = new Publisher($hub_url);
// specify the feed that has been updated
$topic_url = "http://www.onlineaspect.com";
// notify the hub that the specified topic_url (ATOM feed) has been updated
// alternatively, publish_update() also accepts an array of topic urls
