Bad points: 1. Expensive 2. Not all functions mentioned are in the reference, such as "include" 3. Needs more examples. I like two per main concept All in all, if you don't care about $$$, good to have on hand. (I paid $65 in a book store. Amazon had better deal)
We have used PHP3/4 on our own LAN and Web servers for more than two years now and have relied upon the PHP online documentation as well as several popular print books (writing our own when necessary). For the most part we have been disappointed in the printed material. But Blake Schwendiman has finally put together a useful book for the serious developer!
The style and format make it easy to use for both the novice wishing to learn PHP 4, and the experienced developer in need of a useful reference on the shelf. We recommend it for both!
Our only small disappointment was the single chapter devoted to data base support. Data base support is PHP's most powerful feature in our opinion and we expected a bit more. That said, this is a PHP Developer's Guide and not a data base reference, and the information given is sufficient to get you up and running.
Computer developer books by nature quickly become 'dated'. But for the serious developer, this one will serve a long and useful life! Highly recommended!
