The Magpie RSS Parser was created by Kellan Elliott-McCrea in late 2002 to satisfy what he perceived was a lack of practical PHP-based RSS aggregation solutions. The result was a wonderfully capable tool offering a bevy of valuable features, some of which include:

• Object-oriented design: The object-oriented, modularized code allows you to easily integrate the aggregation features into pre-existing applications.
• Highly configurable: Magpie’s aggregation and caching behavior is easily modified through a well-thought-out configuration strategy.
• Feed caching: This very cool feature will cache RSS feeds locally (to the server), conserving bandwidth and increasing application performance.

Distributed under the GPL license, you’re free to use the software without charge and as you please, provided that you abide by the license terms and conditions. Its only requirement is a recent version of PHP (4.0+) compiled with XML (expat) support.
