$feed = new RSS (); $feed->title = "RSS feed title"; $feed->link = "http://website.com"; $feed->description = "Recent articles on your website."; $db->query ($query); $result = $db->result; while ($row = Mysql_fetch_array ($result, MYSQL_ASSOC)) { $item = new RssItem (); $item->title = $title; $item->link = $link; $item->setpubdate ($create _date); $item->description = " $html "; $feed->additem ($item); } echo $feed->serve ();

I hope this article is helpful to everyone's PHP programming.
