AnonymousHere's a little code I wrote up that will parse and display a RSS news feed nicely. You can see it in action here: http://www.blog.jydesign.biz Note the stuff on the right about latest funny stuff. That's a RSS new feed.
Here's the code. Add into index.php Not sure how to use myhacks.php yet, anyone with any pointers will be greatly apprecipated.
