There's a lot of content in my organization that uses PHP in existing web pages and I was wondering if there is a way to use these pages, or rather their PHP code, in Joomla content items.

I know that I could throw them in a wrapper if I was directly linking to them from a menu item, but with many of the pages I'm looking to make them part of an article within a Joomla category so that they will show up when I display all the articles in the category, such as in the Articles » Category / Blog format.

Any ideas on how this might be accomplished?
