Consuming an existing web feed

<?php
class FeedController extends Zend_Controller_Action 
{
    protected $_model;

    public function indexAction()
    {
        // Read remote feed
        try
        {
            $rss = Zend_Feed::import('http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml');
        } 
        catch (Zend_Feed_Exception $e)
        {
            // feed import failed
            echo "Exception caught importing feed: {$e->getMessage()}\n";
            exit;
        }

        // Initialize the channel data array
        $channel = array(
            'title'       => $rss->title(),
            'link'        => $rss->link(),
            'description' => $rss->description(),
            'items'       => array()
            );
        
        // Loop over each item and store relevant data
        foreach ($rss as $item) {
            $channel['items'][] = array(
                'title'       => $item->title(),
                'link'        => $item->link(),
                'description' => $item->description()
                );
        }

        // Pass to view
        $this->view->entries = $channel['items'];
    }

}

Producing your own web feed

Feed Entries: <br />
<dl>
    <!-- Loop through the entries provided by the controller -->
    <? foreach ($this->entries as $entry): ?>
    <dt><?= $this->escape($entry['title']) ?></dt>
    <dd><?= $this->escape($entry['description']) ?></dd>
    <? endforeach ?>
</dl>
