Given the esteem with which the authors are held, one might expect a much better piece of work than this effort. The volume is huge, the coverage of topics much too broad, to warrant the name Core PHP Programming.XML and Generating Graphics are certainly not a core piece of any programming language. Core means syntax, grammar, concepts and the indispensable basics. A mere 100 pages covers eight (8) different databases. There are more than one thousand (1000+) pages in the book ! Database connectivity and processing is probably the single largest application of PHP. You won't learnd much here. The coverage of XML, for example, is similarly shallow. This is certainly not suitable as a textbook. A sad performance by two very important people in the PHP community. From him to whom is given, much is asked. Caveat Emptor.

This was my second PHP book (after the Quickstart series) and it has proven to be one of the few coding books I can't live without. As an introduction to PHP language constructs, it covers enough to get you started with clear text and concise examples. As a reference, it's invaluable!! Good detail of functions and parameters... interesting stuff on design patterns. I wish there was more instruction on the PHP5 object model, but not enought of an issue to bring down the rating.

Overall, a very thorough, clear text.

Now, understand I went into this book knowing NOTHING about PHP, but I did have a background in Perl, HTML, JavaScript, ASP, Visual Basic, C++, CSS, and QBasic. What's another language, right? It seems to me that all the (horribly) negative reviews for this book come from people that didn't understand it. Programming books are written for certain types of people, and most of the myriad of choices are valid for someone. If you do not know what "syntax" means, this book might not be for you.

I purchased this book because it had simple tutorials and a good index in the back. Because I knew nothing about PHP structurally speaking, I needed a few chapters of tutorials to figure out how to do this or that. From there, I relied on their reference for at-a-glance instructions on how to form arrays, or functions. Again, if you do not know what an array is or what a function is, this book is not for you.

When selecting a programming book, whether you have digital bytes running through your blood or just starting out, go to a freakin' book store and thumb through the resources on the shelf. See how they are written. See if they will teach you something productive. Many basic books fail to tell you the transitional steps to make your own code. Many "advanced" books are merely reference code, that are not a very good starting point for people, well, starting out. Some have illustrations. Some have CDs.

For me, this was the perfect guide. In conjunction with PHP.net, there is no task I cannot conquer with this language.

yeah, i had to agree with the negative reviews. this book isn't very good. it reads like bad vcr instructions or something.

So, I thought the negative reviews on this page were kinda suspicious. I decided to buy the book anyways because of all the positive reviews. But, whoa! The negative reviews were right. This book sure is highbrow stuff. I mean, if you're an intermediate PHP programmer, you *might* understand this book. It tends to explain concepts on a high level and leave you to figure out implementation on your own.

On one hand, the book explains very basic concepts about PHP as if you were some sort of newbie. Then, when it has to get to the meat of actually writing code, then the book treats you as if you're a veteran PHP user. Kinda weird.

But, yeah, in general I didn't like this book. I'm no stranger to programming, but this book left me scratching my head.

A PHP book for serious programmers

Core PHP is a book for serious programmers written by people who obviously know the subject inside out. The book is over a 1,000 pages long with densely packed pages. One of the authors Zeev Suraski is the co-creator of the upcoming PHP5 Zend Engine (the heart of the PHP system). The fact that it covers PHP 5 from people involved with that development give it an edge on many older books currently on shelves. The writing style is dry and factual (which is what I want from a technical book). If you have experience with other programming languages such as perl or C/C++ this book could be your rapid transition tool. I have a significant background in Java and a few years ago regarded PHP as just another scripting language that would allow trivial jobs to be done easily and give me sufficient rope to do damage when attempting bigger jobs. I was wrong, and the new features of PHP 5 may help it capture more of the hearts and minds of web developers. Unlike Java there is a shortage of good PHP books.

The tutorial section

The tutorial section covers the basics of obtaining and installing PHP both on Windows and UNIX style platforms. I would have preferred it if they had gone into more details on this subject as I seem to manage to mess up installation and configuration every time I do it under Linux. I always seem to fumble around, missing vital components and when I finally get it working I am not quite sure what it was that made it work. The brevity of the installation instructions are rather summed up by the comment "if you have ever compiled software you've found on the net you will have little trouble with this installation".

The book includes some basic tutorial material at the start but it quickly moves on to topics that would only be of interest to people who have real problems to solve. For example, before page fifty the book covers indirect references to variable names. I found this quite useful as it is something I have wondered about when using other programming languages The book covers the subject of recursion, which is a powerful technique but probably only appropriate for a fairly serious programmer.

Chapter 6 consists of about 40 pages covering PHP and Object Orientation. This is approximately 40 pages more than most PHP books. I have used th OO features of PHP4 but always felt they were a "bolt on afterthought". It looks like PHP5 has integrated OO more deeply into the core of the language. I appreciated the new features of PHP5 such as constructors and destructors, the access specifiers (public, private etc) and abstract classes. It is only a matter of time before PHP5 becomes the default version of the language, so it is a good idea to understand the ideas as soon as possible. It also means you can transfer concepts from other OO languages such as Java and C++. Because the authors are so intimately involved with PHP they were able not only to comment on the changes in syntax in PHP5 but also how it may improve performance in certain circumstances. To quote from chapter 6, "In addition to providing a more intuitive object model, the handle-based system has several additional advantages; improved performance, reduced memory consumption, and increased flexibility".

The function reference

The middle 670 pages of the book are a functional reference covering almost anything you can do with PHP, from interacting with databases to xml processing. Some of the API calls listed struck me as somewhat odd for such a section. For example the interface to the MnoGoSearch search system might be quite useful but is hardly part of every programmers essential PHP toolkit. The function reference also covers System V messages, semaphores and shared memory, hmmm might be a while before I need that information. On the more common front it covers Apache, IMAP, several XML systems and automatically creating and manipulating images and graphics. I couldn't see anything on manipulating flash movies but any geek knows that flash is the work of the devil and everything should be done on the server. The PHP community has created some excellent online documentation for the PHP function calls, but this book would make a good additional commentary for any programmer. Personally I can live with as much explanatory code examples as I can get my hands on.

PHP & Software Engineering

I know that some people do not like to see the words "software engineering" and PHP on the same page. The section on Software Engineering is interesting in that PHP is frequently regarded as a tool for Quick and Dirty style of programming. My comment on this is that Quick and Dirty programming is always dirty and never quick in the long run. This section covers the use of the language features of PHP 5 to implement classic design patterns such as the singleton and factory patterns. It seems like every programmer and his dog has written about design patterns and the Java language and it is a delight to see someone tackle this subject in PHP, particularly using the new features of the upcoming PHP 5 version.

There are some surprising omissions such as a very brief coverage of database independent API's such as adoDB and the pearDB classes. With the pearDB classes now part of the core PHP distribution this seems a surprising omission. For me database portability is important, I would like to be able to at least easily port my code between popular databases. I could find no mention of SQL Lite, one of the features due to be bundled with PHP5 when it ships.

In summary

A good comprehensive reference, not for beginners. A combination of this book, a "cookbook" style reference and the web documentation and you are set for programming anything with PHP.

One of my key concerns when reviewing a good book is the pull between information density and a light, easily read style. I believe that as we get further along the learning curve we can sacrifice some readability for density -- we want more facts and less explanation.

The authors of Core PHP Programming have found a marvelous middle ground. Toward the beginning of the book they have a great deal of light, explanatory material as they cover the basics of PHP. As they move towards more advanced topics there is less explanation and a tighter packing of information. At the same time the book has a large number of small code examples throughout, making sure that you know how to use the functions under discussion.

This is the third edition and I must admit that I had not come across it in either the first or second editions, so I have no great way of comparing them in this review. It has certainly been revised to take into account the changes for PHP 5 and examining the table of contents for the second edition on Safari I can see the that the basic structure has remained the same while the book has grown about 300 pages. The addition of Zeev Suraski as co-author can only be to the benefit of the quality of the information, particularly regarding PHP 5.

The book starts with the absolute rock bottom of PHP, the basic data types and operators through to efficiency, debugging and design patterns. Along the way it covers almost all aspects of PHP 5 with a readable reference style. The `Core' in the title of this book is a key to understanding it. If you're looking for a book with all the code required to handle session management, or user logins and security (to mention two possibilities) then this isn't the book for you. If, however, you are after a book that more than adequately explains the power and nuances of PHP and programming in the language then this is a marvelous volume.

It's broken up into 5 sections: "Programming PHP," which covers the basics of data, control flow and I/O; "Functional Reference," which is 600 odd pages broken up into 12 chapters that seems to cover every PHP function (a check of three sub chapters showed every function mentioned on the topic at PHP.net was also in the book) and does it well with good explanation and code examples; "Algorithms," which details a number of methods of performing routine tasks such as sorting, parsing and generating graphics; and "Software Engineering," devoted to design, efficiency and design patterns; and finally, there are a seven excellent appendices.

Taken as a whole it does a good job of covering the whole language and the ways of using it.

I can imagine it would make a good companion volume to my other favourite PHP volume, PHP and MySQL Web Development, which tends more towards recipes and leaves out the encyclopedic coverage of this book.

Leon Atkinson has a good web page for the book that includes a link to download all the code and examples, a link to the Prentice Hall page for those wanting an example chapter or a look at the Table of Contents and some other reviews. His site also has a page for the inevitable errata, currently blank. While I did find only one typo (not in example code) I can't claim to have read every page or run all the code examples.

I'd recommend this volume to anyone who wanted a comprehensive guide to PHP 5. It is probably useful at almost all levels.

This is by far the best PHP book on the market.

If you want a good intermediate to advanced book that includes: a solid tutorial of the syntax of PHP, an excellent function reference with good examples (99% of the examples worked for me), coverage of the new PHP5 capabilites, useful set of algorithms for common how-to features, and common sense guidelines on building, debugging, patterns, and Object Oriented php design, then this book will not disappoint.

If youre looking for a dummies how-to book to get your database driven website up and running, don't buy this book. And don't complain when you do buy the book and it turns out to be not what you thought - you need to be willing or at a stage to invest the time and effort to learn PHP in depth.

If you want a great reference and set of guidelines and algorithms, and are willing to extend yourself, then you will like this book.

This book just flat out sucks. The negative reviews say it all, so I won't waste time writing up the same stuff they did.

First, I'll admit that I'm biased against PHP because it's such a haphazard language. I was frustrated to no end to find out that they made a huge change to the object model with this PHP 5. But, since it's helpful to know PHP, I figured I would grab a book that was written by the authoritative gurus on PHP. With that having been said ...

What a joke! This isn't a programming book, it's a memoir! The authors explain PHP only to the extent to which it allows them to glorify themselves and the open source community (or as I like to call it: the confoundingly elitist hippy brigade.

Part 1 is actually the most useful part of this useless book. It walks you through the basics of the language. Thankfully, it has the most examples so you can do some real learning instead of listening to their pie-in-the-sky abstraction ideas. Part 2 calls itself a "functional reference", but it's anything than that. Each entry gets a paragraph talking about the language element. But, there's no indication of how to use it -- not even an example in most cases! Furthermore, part 3 and part 4 of the book are totally useless. Yes, they explain how to code a nice sorting algorithm, use nifty graphics manipulators, and how to write efficient code. But, honestly? If you were writing code in another language, you could buy modules for sorting and graphics for about $10 each that are far easier to use and more powerful than what's given in PHP. This book doesn't cover all the bases it should about writing code well - they dedicate anout 25 pages to the subject. And, if you're concerned about writing efficient code and building sorting routines from scratch yourself, go take a class and learn to do it right! (Hint: this book actually shows you how to do it INcorrectly on occasion.)

Save your money and try one of the "customers who bought this also bought" because that will tell you where customers turned to after this book completely disappointed them.

I read the reviews before I bought the book. Sadly, I should have listened to the negative reviews. This book is NOT what it's advertised. I agree with the other reviewer: this is not a "CORE" book. Rather, it's more of an intellectual discussion of PHP on an abstract level. If you know the syntax, and want to learn how to apply it, then this book may be to your liking. However, DO NOT expect a reference guide!!! This book does not take the time to document the language. This isn't the kind of book you keep at your side while you code. You read it, absorb it's wisdom, and then proceed.

Why did I give the book two stars? Two reasons: 1. Because a core book should be just that: core material (i.e.: a reference, a code example, and a best practices guide.) This book is a conceptual teaching guide. Which is fine, but, I already know how to code. I wish this book would have been more direct to begin with. 2. The book is a rather boring read. I once agree with the other reviewer: I could have done without all the self-congratulatory text. As for the meat of the book, it was rather amateurish and cutesy, the way Japanese instruction booklets are. All in all, mostly disappointing.

I have to agree with the negative reviews - this book just doesn't make any sense. First of all, why call it "Core" PHP? There's no core to this book. There's no syntax description, no documentation on arguments, returned values, or errors. There's very few examples of code, even the new version 5 code. This book should have been called "Addendum to a previous reference" instead of Core.

Personally, I distaste the format and style of the book. The first chapter glorifies the history of PHP to make you think it's bigger than Jesus. Guess what, folks? PHP has a long way to go before it's deserving of such praise. If I wanted an editorial, I would've gone to the "fiction" section of my bookstore.

Lastly, the positive reviews on this site are obviously written either by the authors or by people with affiliations with this publications. Come on, guys. Shouldn't you spend less time pumping up your diatribe novel, and more time writing a useful book on a fledgling programming language?

Great combination of PHP programming basics, function reference, how-to and guidance on project development. I was pleasantly surprised with the depth of coverage and extensive sample code.

Brings you up to date with the new PHP5 changes and zend engine improvements. You can't go wrong.

And to previous one star reviewer: Jason Fortuny from Kirkland WA, one look at his wish list will tell you a few things about whether to take his review seriously.

I read some of the negative reviews, and I must say they are completely off the mark .One of them waffled on about how this is not for inexperienced PHP propgrammers, freely admits he is not experienced, then continues to review the book anyway. Why write a negative review simply out of frustratoin at your inability to appreciate the level the book was written for?

Dont blame the author for your lack of experience. Instead, go away and get some experience and come back to Core PHP, and maybe then you will start to appreciate its value. It's like an 11 year old trying wine for the first time, spits it out and says "yuck". The refined adult wine drinker knows how to appreciate it. 4.5 stars from me.

This book achieves what it sets out to: A core reference on php. It won't teach you how to implement a silly pet store with a mysql database. But it will be a useful resource and a great reference to the language, functions sorted according to meaningful chapters with excellent poignant examples, and how-to's for common real-world problems, then this is for you. If you want to learn how to develop a web application according how someone else thinks you should design it, then go for the more popular tutorial-style books. If you want a desktop reference that you can rely on when you need the facts then this is it.

The reviewers who gave this low stars probably want their hand held thru a join the dots web project. If you are a serious PHP web application designer who values creativity and flexibility and wants more than a tutorial, you'll be impressed with Core PHP, 3rd Edition. It also covers PHP 5 improvements to the language as well. Maybe thats why the script kiddies are wary because PHP is moving away from procedural script-in-html mode into the Object Oriented world of component driven design.

There are great chapters on software engineering, efficiency, integration, and design patterns that will be invaluable to the PHP architect. As are the full descriptions of configuration variables and interacting with your environment.

I'm not impressed. The online documentaion at php is as good and its free.Also if you are new to php... stay away from this book try PHP and MySQL Web Development by By Luke Welling, Laura Thompson. That book is truly awesome. I bought both these books and I never use Core PHP Programming.

This time around Leon Atkinson teamed up with Zeev Suraski, one of the PHP project's team members and co-developer of the Zend Engine -- the scripting language that powers PHP. Structurally, the book is laid out very much the same as it's predecessor. There are four parts followed by several appendices. This format works well and is easy to navigate. The layout has a more polished look to it.

One of the many things I really enjoy about this book are the examples that are provided, they are concise but well thought out and usually show related functions that help with code generation. As a heavy Index user I am happy to say that this one doesn't disappoint. Some effort was put into organizing this information, for people like me, to thumb through and find things quickly. The book has been updated to include the full features for PHP 5. This is good for those of us who have dealt with feature creep over the years and get stumped by subtle changes in the way functions work.

I highly recommend this book. It is a great resource for the PHP programmer regardless of skill level.

How can you convey the power, the flexibility and the simplicity of a relatively new language without loosing any of your audiences, beginner to advanced, along the way?

I have been a programmer for over 6 years, but have never had the pleasure of doing anything with PHP before I started reading this book. I must say, I was totally impressed after I had finished reading Leon's book. The PHP language itself has grown tremendously over the past 8 years or so, and I can certainly see why it is so appealing to users of all levels. The author of the book, Core PHP Programming, does an amazing job explaining the nuance of PHP that any level READER can understand the topic and does whatever it is that he or she is after - which would be designing a dynamic web site in this case.

Leon starts the book with the paraphrase "...answer is that PHP is better" and goes on to explain why that is the case. His answers would compel any PHP user or potential users:

1) PHP is free
2) PHP runs on UNIX, Windows, and Mac OS X
3) PHP is modifiable
4) PHP was written for Web Page creation
5) Support for PHP is free and readily available
6) PHP is popular
7) Programming skills developed in other structured languages can be applied to PHP

By the end of page 11 (5 pages into chapter 1) the reader is hooked and wants to read on to find out what all Leon is talking about. All the key phrases are there: free, extendible, lots of supports, and ease of use.
By the end of Chapter 7 or page 160, you are ready to rock. By now, you know what PHP is all about and have learned its syntax, features, and have even looked (or hopefully written) some code.
Dynamic Function Calls ends chapter 4. This section CLEARLY shows to any programmer how powerful PHP really is and how easy it would be for anyone to utilize that power. Dynamic Function Call is very difficult to implement in Java (I don't know of any way to do in C++ actually - specially in one line of code). In one line of code PHP is able to accomplish this task. Very powerful stuff...
I was personally very impressed with the OO features of the language, which was depicted very well in chapter 6. I also need to say that Leon's introduction to Objects and Classes are very easy to understand for users new to the topic.

For the next few hundred pages, in Part II of the book - Functional Reference, various functions that PHP supports are shown and each one is explained in a great detail. Most of the functions have also been followed by an example that shows the usage each function just described. These chapters are very good reference even for the advanced users as PHP has grown so much that keeping track and memorizing of all the functions would be nearly impossible.
Leon ends the book with a section called Software Engineering. The two chapters that I liked in this section were the design and the design patterns chapters. Chapter 27, Design, is basic software engineering practices in a nutshell. Something that took me over two graduate level courses to cover, the author gives an overview in about 25 pages. I recommend this chapter to any novice programmer. The chapter on Design Patterns is simply put, great. 4 Design Patterns from the popular GoF book are described:
i) Singleton
ii) Factory
iii) Observer
iv) Strategy
A reader can benefit the specific examples that are given in this chapter as they apply to Web site design and implementation. The examples given are reusable and would benefit any user of PHP.
Throughout the book the author does a very good job at showing the reader what the differences between PHP and other languages are. I think PHP would be a very good first language to learn b/c it has all the features of other popular scripting languages such as Perl and structural/OO languages such as Java and C/C++.

It has been a great pleasure reading and learning from this book. The author Leon Atkinson has been an inspiration to me to learn this programming language. Without a doubt I believe this to be the best source for information and coding options on PHP. If you really want the very best resource for your own PHP projects you won't be sorry if you purchase this guide.

In what seems like a dazzingly short time, PHP has grown from a simple little language that dynamically generates web pages to a fully fledged object oriented language. Now available in its fifth major revision, PHP code looks so much like C, with the added benefit of being OO. PHP is still very specialised, confined to essentially web server applications. While it is true that PHP is no longer strictly confined to this, the de facto reality is that the vast majority of applications, and the concomitant employment prospects, are in the context of web servers.

Clearly, if you are a web programmer, knowing PHP is a big plus. A hardcore way of doing this is to use the online documentation scattered throughout the web, and learn by downloading and analysing code examples. PHP veterans, including maybe the authors, probably did this. Nothing better at the time. While it works for some, this approach is awkward to many, and is quite ad hoc. The danger is in learning quick kludges as opposed to methodically designing and coding, with a full appreciation of the language's extent. Luckily, as PHP has matured, you can turn to this book for a logical pedagogy.

The treatment is exhaustive and shows starkly how far PHP has come. For example, you can use all the major encryption algorithms (Rijndael, Serpent, DES...) as extensively and easily as though you were coding in C. On another tack, the image analysis routines now handle all the important image formats (GIF, JPEG, TIFF...). The book displays the breadth of such computing topics now available, and the wealth of library routines in each topic describes the depth of the treatment.

Are you familiar with Fortran and the IMSL mathematical package so often associated with it? Or with C++ and its standard template library? Or C and the Numerical Recipes routines? If so, this book lets you appreciate that intellectually, PHP now ranks with those luminaries.

Hands down the best PHP book i've read to date, Core 2 is a close second. Was easy enough to bang out in a long weekend and kept me juiced to learn more!

Well Done!
