"Upgrading to PHP 5" book....
Ah. Sounds like I need to order the book.
Its a good book for developers, but if you're just looking to install it and be done, I can probably email you an excerpt. I think 1 page is legal, so long as I don't charge you. :)
Of course once I get better at Ruby, I may not be going back to PHP at all... :)
Except that PHP will be out there, all over the place, and you'll either have to work with it or be prepared to convert it all to Ruby.
That's why I'm lucky to be a [Sys|SAN ]admin for real, and a developer only for pretend. I can usually rewrite my own code. In seriousness though, PHP5 is a cool language, handles threads, and is still faster than Ruby, so I'll likely be keeping my skills sharp on both.
