Beginning PHP4 offers an almost ideal introductory tutorial to one of today's hotter scripting languages. This book really is everything that the novice needs to start building dynamic Web sites that are powered by PHP4, but old hands at programming also will find in it valuable information.
PHP, of course, is introduced in the book, but there's also an approachable and effective introduction to programming in general. The conscientious tutorial on basic concepts like variables, keywords, and flow control will give even beginners an understanding of the basics of writing programs. PHP, it turns out, is not only a great way to generate HTML dynamically, but a very marketable skill. Web fundamentals like HTTP, HTML form variables, and managing session information using no less than four different techniques are explained thoroughly and effectively. You also find out how to install PHP and other tools on your system, with the assistance of plenty of screen shots.
That's not to say that this book will cramp the style of more experienced developers. Some chapters delve into such important and advanced topics as database programming (with MySQL) and PHP's support for XML. One standout section demystifies the new support for objects and classes in PHP4. Basic topics like managing files and directories on the server, plus graphics processing, are addressed, of course, and a nifty sample program shows you how to build a Web-based text editor. Except for the final case study--a "URL directory manager" (akin to Yahoo!) that's rather specialized--the examples are right on, and illustrate everyday programming tasks. You'll learn also how to generate e-mail with PHP--certainly a valuable skill to have.
The appendix lists several hundred PHP functions in over 50 pages--a handy and useful feature. In all, Beginning PHP4 provides a strong choice for learning about one of today's most powerful and easy-to-use scripting languages; it's concise, fast moving, and thoroughly approachable. --Richard Dragan

Reviews From AMAZON.COM
I went from Zero to Expert and this book was a big help
I like this book and highly recommend it. It is good for people who are new to PHP but not so good for people who are new to programming. I've done a lot of programming in other languages and needed to learn PHP in a big hurry for a project that I was about to take on. This book got me up to speed fast. I'm inclined to think that a lot of the negative reviews are from people without any programming background. I agree this book is not the right place to start if you are a non-programmer. I've also done a fair amount of html prior to reading this book, I found that it's html section and php techniques for generating forms was really excellent, I learned some really great things!
As far as depth goes, such as discussing details of the functions. Well, that's what the php manual is for (www.php.net). Initially I tried to learn the language from the php manual alone but didn't get very far, I couldn't see the forest because the trees were in the way, eg too much detail without a big picture. What this book does is to focus on the big picture of how and why to do something. It also shows multiple approachs to the same problem and compares them so that you get an idea of the alternatives and trade-offs.
Starting from not knowing php to writing some very sophisticated programs... I learned it all with two books and the manual. The other book that I read is PHP Developers Cookbook. The two books are very complimentary, there is not that much overlap between them instead they fill each others gaps. Note that the "Cookbook" is more advanced and assumes that you already know a lot of php.
Okay, the one big gripe that I have is their lack of proof reading. They must have really rushed this to press. There are literally hundreds of errors and the errata sheet is incomplete. However it is easy to get past the errors as long as you don't make the assumption that the text is always correct. In other words, if something doesn't make sense then you should be suspicious of an error instead of always assuming that it's your lack of understanding.
The necessity of Rewriting the code examples is a little annoying, but the book can hardly be faulted for language changes that were made after the book was published. PHP is a rapidly moving target, no book will ever be current for very long. And besides, the best way to understand a program is to take it apart and rewrite it, that's why they are called "Examples". (most of the changes needed are trivial).
Mostly what you need to do is to change $varname to $_REQUEST['varname']
and that will fix it. If you are having trouble finding the correct variable then use
phpinfo();
to get a list of all of the available variables, then you just pick what you need from the list and put a $ in front of it.
(...)By the way, the code examples can be downloaded from their website which can save a lot of typing...
It Gets The Job Done, But It's Nothing Special
If you've been programming for a while, the pace of this book is too slow to read cover to cover. The best thing to do is read the first half of the book (through chapter 9) and then skip around to what interests you. As others have mentioned, you will have to modify the code in the examples to get them to work because of the use of globals. This is not impossible to overcome if you write the message board for the book at http://p2p.wrox.com. However, it is annoying. There are other errors too, but it doesn't take much in the way of trial and error to get around them. The three chapters on MySQL are the most useful. If you've worked with databases in other scripting languages, e.g. Perl, Python, or Ruby, it's simply a matter of looking up what you want to do. There are some good style examples on structuring PHP code - use of an "$action" variable to drive the behavior of the site from a single page. The book also stresses putting reusable code in include files. The author dismisses classes/objects as not really being useful in PHP, but the use of classes elimates the need for the "global" declarations in many of the common include files. All in all, this is an adequate book, but noting profound. If you have programming experience, this book will get you up and running quickly.
