Zend\Feed enables developers to retrieve feeds via
you know the URI of a feed, use the
to consume it:
$feed = Zend\Feed\Reader\Reader::import('http://feeds.example.com/feedName');
Importing requires an HTTP client
To import a feed, you will need to have an HTTP client available.
If you are not using zend-http, you will need to inject
Readerwith the HTTP client. See the section on providing a client to Reader.
You can also use
Zend\Feed\Reader\Reader to fetch the contents of a feed from
a file or the contents of a PHP string variable:
// importing a feed from a text file $feedFromFile = Zend\Feed\Reader\Reader::importFile('feed.xml'); // importing a feed from a PHP string variable $feedFromPHP = Zend\Feed\Reader\Reader::importString($feedString);
In each of the examples above, an object of a class that extends
Zend\Feed\Reader\Feed\AbstractFeed 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\Reader\Feed\Rss object would be returned. On the other
hand, if an Atom feed were imported, then a
is returned. The import methods will also throw a
Zend\Feed\Exception\Reader\RuntimeException object upon failure, such as an
unreadable or malformed feed.
Dumping the contents of a feed
To dump the contents of a
Zend\Feed\Reader\Feed\AbstractFeed instance, you may
assert($feed instanceof Zend\Feed\Reader\Feed\AbstractFeed); // dump the feed to standard output print $feed->saveXml();
