I'm about to start work on a new project and thought it could be a good time to also start looking into a new PHP CMS. I've really only spent a lot of time with Joomla, so "new" can almost be "any".
Anyway, I've also been seeing a lot of talk about A/B testing and thought that it might be a good idea to try. From what I've seen, there's a couple of solutions for Rails, but I was wondering if there are any out there that support PHP CMSs? The more integrated, the better.
Thanks for any suggestions or thoughts...
