New on ZendCasts.com this screencast helps you use the Zend Framework's Zend_Feed component to create simple RSS and Atom feeds for your application.
The screencast shows you how to create a basic controller with information for a sample blog post (title, date creates, content, etc) and a simple method to create default posts. A second controller is made to handle the feed creation and two actions are created - one for RSS and the other for Atom. The posts are then parsed and pushed out to views for displaying as feeds.
The site has more great screencasts where this came from so check out their screencasts section for ones on other topics like ZendX_JQuery, working with Zend_Log, and validation with Zend_Validate.
