... and it's not for people who can't figure out which version of PHP they're running. I had no problem running the code against PHP 5. There's a /whole/ bunch to wade through, code-wise, but so far I'm liking it. There's a lot of stuff in there that I can use.
It does seem a strange to me that they'd publish a book on PHP 5 while it's still in flux, but I guess everyone's racing to be first.
