Introduction
Zend_Feed provides functionality for consuming RSS and Atom feeds.
It provides a natural syntax for accessing elements of feeds, feed attributes, and entry
attributes. Zend_Feed also has extensive support for modifying feed
and entry structure with the same natural syntax, and turning the result back into XML. In
the future, this modification support could provide support for the Atom Publishing
Protocol.
Programmatically, Zend_Feed consists of a base
Zend_Feed class, abstract Zend_Feed_Abstract
and Zend_Feed_Entry_Abstract base classes for representing Feeds and
Entries, specific implementations of feeds and entries for RSS and Atom, and a
behind-the-scenes helper for making the natural syntax magic work.
In the example below, we demonstrate a simple use case of retrieving an RSS feed and
saving relevant portions of the feed data to a simple PHP array, which could then be used
for printing the data, storing to a database, etc.
Be aware
Many RSS feeds have different channel and item properties available. The RSS
specification provides for many optional properties, so be aware of this when writing
code to work with RSS data.
