Creating Your First RSS Feed: Creating Your First RSS Feed Some content management systems will generate feeds for you, and there are several RSS-creation tools (both free and not-so-free) available. But even without these tools, it’s easy to create an RSS feed yourself. There are two basic ways to approach your first RSS feed: you can bake it from scratch or connect to a database.


Bake it From Scratch : Bake it From Scratch All RSS feeds are in XML format. XML is a markup language, and as such it looks very similar to HTML; it uses tags to “mark up” content. But unlike HTML, in XML you can make up your own tags, and these tags don’t control the presentation or “look” of a site. They simply define and describe your content.


Bake it From Scratch: Bake it From Scratch With a few simple steps, you can create your first RSS feed from scratch. All you need is a text editor (eg. Notepad) and some compelling, frequently updated Web content.


Bake it From Scratch: Bake it From Scratch Declare the RSS version you’re using (2.0 is the latest) with the tag Use the tag to begin your feed Use the , , and tags to describe your feed as a whole (there are other optional tags that apply to your feed as a whole, like , , and )


Bake it From Scratch: Bake it From Scratch Start each item with the tag Within each item, add a , , and End each item with End your feed with End your file with Save your files as an XML file (eg. sciencenews.xml)

That’s it! : That’s it! Now upload your .xml file to your server and subscribe to your feed using your feed reader. Voila!


Connect to a Database : Connect to a Database Of course, it’s easy enough to create a feed like the one above. The trouble comes with maintaining and updating it. If you create your feed from scratch, you’ll be adding new items from scratch too. That can get very tedious very quickly.

Connect to a Database: Connect to a Database Set the header Use the header() function to make sure your PHP send the text in your feed as XML and not HTML. Enter this line of code at the top of your file:


Connect to a Database: Connect to a Database Declare the RSS version your using (2.0 is the latest) with the tag Use the tag to begin your feed Set the basic feed using the same , , and tags as you would if you were baking from scratch.


Connect to a Database: Connect to a Database Retrieve the items from your database First, you need to write a mySQL query that grabs the items you want to include in your feed. This query grabs the reference number, headline, body text, and publication date for the most recent 10 releases with a category of “humanities and social sciences” and lists them in descending order by date.


Connect to a Database: Connect to a Database Next, you need to store the query results in an array. The next piece of code looks like this:

In other words, you need to format the title, description, and link for each of the items you’ve grabbed from your database. That code looks like this: http://www.rochester.edu/news/show.php?id= No recent Press Releases found.
