When I run the hard-coded '&' operation (the > commented out echo), it returns 2. I'm stumped. In PHP a boolean true also equates to 1. You are using the & operator though, instead of the && which I think you're looking for. They both do different things. Sorry, it's late and I've been befriending mr Jack Daniels a little tonight, so forgive me if my answer is as close to what you were looking for as is 42 (life the universe and everything) to The Question.
