New from Matt Wade (of CodeWalkers), there's a piece over on DevArticles talking about the creation of a news system in PHP.

So, you want to display news on your site? Think it'd be pretty cool to have a page where you can enter something each day and then the whole world gets to see it? Well, I'm here to tell you how in this lesson of "Creating a News System". He starts from the roots of the system, planning out the forms to input the information (in this case, news) into the database. His script then submits to itself, and enters the information into a file on your local filesystem for storage. There are lots of ways to store this data, and a file has it's advantages - cross-platform stability, for one.

He finishes up the article with the script that pulls your news from the file, and even a small script that can filter and edit/delete a news item from the text file. It's all one script (for simplicity sake), but it's a good place to start...
