class RSS{ var $title; var $link; var $description; var $language = "en-us"; var $pubDate; var $items; var $tags; function RSS() {  $this->items = array();  $this->tags = array(); } function addItem($item) {  $this->items[] = $item; } function setPubDate($when) {  if(strtotime($when) == false)   $this->pubDate = date("D, d M Y H:i:s ", $when) .

  " . $this->link . "\n";  $out .= "
  
   " . $this->description . "
  \n";  $out .= "
  
   " . $this->getPubDate() . "
  \n";  if($this->attachment != "")   $out .= "
  ";  if(empty($this->guid)) $this->guid = $this->link;  $out .= "
  
   " . $this->guid . "
  \n";  foreach($this->tags as $key => $val) $out .= "<$key>$val
  ";  $out .= "
 \n";  return $out; } function enclosure($url, $mimetype, $length) {  $this->attachment = $url;  $this->mimetype  = $mimetype;  $this->length   = $length; }}

Example:

$feed = new RSS();$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();
