Offline reference for php and mysql?

Question

PHP

A vacation is planned, which I plan to spend with "grandfather in the village", and start my own project. But due to forgetfulness and the lack of the Internet, I would like to know if there are any good and not overloaded with water reference books on peha (what we give, what we get, in what order, and a couple of examples) and bases?
And preferably not a scan to pdf, but that, at least with a native search, you could run through the text.
thanks ahead of time)
