In a previous post crynobone shared a method for creating RSS feeds from the information stored in a database. He's back this time to handle just the opposite - gathering the data from multiple RSS feeds into a simple aggregator.
What is RSS Aggregators? Why you may already familiar with Feedburner, Live.com, My Yahoo and Google Personalized Page as well as other News Aggregators where you have freedom to control your own News. Here your chance All we do need is to get Magpie RSS parser for PHP and some AJAX coding to create our very own News page.
As mentioned, the entire setup revolves around the MagpieRSS library, making it a simple task to pull in and work with the contents of remote RSS files. He even shows how to use a simple Ajax connection to request the latest updates you've fetched and stored in the database.
