I am a web developer with experience in multiple languages.
I'd say, this book is good, but not "great", and definitely not a "bible" (if you consider the bible a good thing).
---Part 1(PHP) is very well organized, and gives you an ordered path to learn PHP.
---The same goes with part III(advanced PHP).
---It gives a chunk of useful PHP things at the end in part V.
---Part 2 was nearly horrifying. Seeing as how this book was written even before PHP 6 came out, you would assume the authors would stop using deprecated HTML tags. Also, when is says "PHP and MySQL", it means exactly that. The author is assuming you already know SQL, and tries to throw in the whole SQL language in maybe a chapter and a half.
YOU PICKS (Things I don't care about, but some people might, I didn't read most of these)
---Part IV has a bunch of chapters explaining how to work with other databases (postgreSQL, Oracle, etc)
---Part VI has some case studies(which I read, but you know...)
---The appendix has some references for C, Perl, Pear, and HTML backgrounds.
All in all, I think it is worth getting, but don't bother getting a $70 new copy thinking it will be a life-long reference... get the $5 used one, and when you're done, it probably won't have a very prominant place on your bookshelf.
