## 4.2. Importing Feeds with Zend_Feed

`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.
