PHP Implementation of the RSS generation class instance

This article mainly introduces the PHP implementation of the RSS generation class, example analysis of the RSS generated class principle, definition and use of skills, very practical value, the need for friends can refer to the

This article describes the RSS-generated class for PHP implementations. Share to everyone for your reference. Specifically as follows:

Use the example below:

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14-15 16

$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); $item->description = "<! [cdata[$html]]> "; $feed->additem ($item); echo $feed->serve ();
