Instances of RSS generation classes implemented by php, examples of phprss generation

The examples in this article describe the RSS generation classes implemented by php. Share it with everyone for your reference. The details are as follows:

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) . "GMT";
  else
   $this->pubDate = date("D, d M Y H:i:s ", strtotime($when)) . "GMT";
 }
 function getPubDate()
 {
  if(empty($this->pubDate))
   return date("D, d M Y H:i:s ") . "GMT";
  else
   return $this->pubDate;
 }
 function addTag($tag, $value)
 {
  $this->tags[$tag] = $value;
 }
 function out()
 {
  $out = $this->header();
  $out .= "<channel>\n";
  $out .= "<title>" . $this->title . "</title>\n";
  $out .= "<link>" . $this->link . "</link>\n";
  $out .= "<description>" . $this->description . "</description>\n";
  $out .= "<language>" . $this->language . "</language>\n";
  $out .= "<pubDate>" . $this->getPubDate() . "</pubDate>\n";
  foreach($this->tags as $key => $val) $out .= "<$key>$val</$key>\n";
  foreach($this->items as $item) $out .= $item->out();
  $out .= "</channel>\n";
  $out .= $this->footer();
  $out = str_replace("&", "&", $out);
  return $out;
 }
 function serve($contentType = "application/xml")
 {
  $xml = $this->out();
  header("Content-type: $contentType");
  echo $xml;
 }
 function header()
 {
  $out = '<&#63;xml version="1.0" encoding="utf-8"&#63;>' . "\n";
  $out .= '<rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/">' . "\n";
  return $out;
 }
 function footer()
 {
  return '</rss>';
 }
}
class RSSItem
{
 var $title;
 var $link;
 var $description;
 var $pubDate;
 var $guid;
 var $tags;
 var $attachment;
 var $length;
 var $mimetype;
 function RSSItem()
 { 
  $this->tags = array();
 }
 function setPubDate($when)
 {
  if(strtotime($when) == false)
   $this->pubDate = date("D, d M Y H:i:s ", $when) . "GMT";
  else
   $this->pubDate = date("D, d M Y H:i:s ", strtotime($when)) . "GMT";
 }
 function getPubDate()
 {
  if(empty($this->pubDate))
   return date("D, d M Y H:i:s ") . "GMT";
  else
   return $this->pubDate;
 }
 function addTag($tag, $value)
 {
  $this->tags[$tag] = $value;
 }
 function out()
 {
  $out .= "<item>\n";
  $out .= "<title>" . $this->title . "</title>\n";
  $out .= "<link>" . $this->link . "</link>\n";
  $out .= "<description>" . $this->description . "</description>\n";
  $out .= "<pubDate>" . $this->getPubDate() . "</pubDate>\n";
  if($this->attachment != "")
   $out .= "<enclosure url='{$this->attachment}' length='{$this->length}' type='{$this->mimetype}' />";
  if(empty($this->guid)) $this->guid = $this->link;
  $out .= "<guid>" . $this->guid . "</guid>\n";

  foreach($this->tags as $key => $val) $out .= "<$key>$val</$key\n>";
  $out .= "</item>\n";
  return $out;
 }
 function enclosure($url, $mimetype, $length)
 {
  $this->attachment = $url;
  $this->mimetype  = $mimetype;
  $this->length   = $length;
 }
}

Usage examples are as follows:

$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();

I hope this article will be helpful to everyone’s PHP programming design.
