MagpieRSS: RSS for PHP

It provides an XML-based (expat) RSS parser in PHP.

It is compatible with RSS 0.9 through RSS 1.0. Also parses RSS 1.0's modules, RSS 2.0, and Atom.

• Easy to Use
• Parses most RSS formats, including support for 1.0 modules and limited namespace support. RSS is packed into convenient data structures; easy to use in PHP, and appropriate for passing to a templating system, like Smarty.
• Caching the parsed RSS means that the 2nd request is fast, and that including the rss_fetch call in your PHP page won't destroy your performance, and force you to reply on an external cron job. And it happens transparently.
• HTTP Conditional GETs
• Configurable
• Makes extensive use of constants to allow overriding default behaviour, and installation on shared hosts.
• Modular
