Zend_Feed enables developers to retrieve feeds very easily. If you know the URI of a
feed, simply use the Zend_Feed::import() method:
<?php
$feed = Zend_Feed::import('http://feeds.example.com/feedName');
?>
You can also use Zend_Feed to fetch the contents of a feed from a file or the contents
of a PHP string variable:
<?php
// importing a feed from a text file
$feedFromFile = Zend_Feed::importFile('feed.xml');
// importing a feed from a PHP string variable
$feedFromPHP = Zend_Feed::importString($feedString);
?>
In each of the examples above, an object of a class that extends Zend_Feed_Abstract is
returned upon success, depending on the type of the feed. If an RSS feed were retrieved via one of
the import methods above, then a Zend_Feed_Rss object would be returned. On the other
hand, if an Atom feed were imported, then a Zend_Feed_Atom object is returned. The
import methods will also throw a Zend_Feed_Exception object upon failure, such as an
unreadable or malformed feed.
