I would like to maintain online PHP code using wiki-like features, such as: ‘edit this page.’ Also: page rollback, site versioning and site staging features would be nice. Such a thing should ease web service collaboration. Any recommendations?

What I want almost sounds like a WikiWithProgrammableContent for PHP. Almost, but not quite. I desire complete control, not just programmable extensions. And, I must admit, I’m not interested in facilitating the WikiWay.

Ariadne is a web application server that appears to fit the bill, except it seems too bulky. Wiki-like simplicity is what I desire. It does offer a nice, syntax-highlighting online PHP editor.

Edit This Page PHP sounds like it would work, with a little modification. If I want to modify an existing system, however, what would make the best foundation?

Many thanks.

Do you know a good WikiEngine for editing PHP code online?
