Writing RSS Feeds

Problem

You want to generate RSS feeds from your data. This will allow you to syndicate your content.

Solution

Use this class:

class rss2 extends DOMDocument { private $channel; public function __construct($title, $link, $description) { parent::__construct(); $this->formatOutput = true; $root = $this->appendChild($this->createElement('rss')); $root->setAttribute('version', '2.0'); $channel= $root->appendChild($this->createElement('channel')); $channel->appendChild($this->createElement('title', $title)); $channel->appendChild($this->createElement('link', $link)); $channel->appendChild($this->createElement('description', $description)); $this->channel = $channel; } public function addItem($title, $link, $description) { $item = $this->createElement('item'); $item->appendChild($this->createElement('title', $title)); $item->appendChild($this->createElement('link', $link)); $item->appendChild($this->createElement('description', $description)); $this->channel->appendChild($item); } } $rss = new rss2('Channel Title', 'http://www.example.org', 'Channel Description'); $rss->addItem('Item 1', 'http://www.example.org/item1', 'Item 1 Description'); $rss->addItem('Item 2', 'http://www.example.org/item2', 'Item 2 Description'); print $rss->saveXML();
