this is a good book, good review of the php4 language, but useless if you want to get a PHP5 certification.

I buy the book cause i want to make the certification on PHP5 so i wasted my money...

Could help if the title of the book specify the language version.

This book was a good overview, but be careful. There are numerous mistakes in the book and on the "practice" tests. Not that his book will even be worth anything since the PHP4 test will no longer be given in a month, but if it's any indicator of what the PHP5 book is like I recommend you use more then one source of study material. Certain topics that are in the test were very briefly covered in the book, but I had two or three questions on it. I would recommend the cert course through Zend if you are worried about your knowledge.

When studying for a technical certification exam, there are two things that you must do. The first is to achieve the appropriate level of expertise and the second is to become familiar with the forms that the questions may take. Questions on technical examinations can be very tricky, a common cause of failure is to misread or misinterpret the question. Programming is such a precise activity that it is easy to write a question where the "obvious" answer is in fact wrong.
While this book does have some description of how to program in PHP, it is a review only and there is not enough to impart the appropriate level of expertise in PHP. A small number of sample questions are given at the end of each chapter and there is a sample exam with eighteen questions at the end. Solutions to all of the questions are included.
Although I found the study questions to be good, my personal opinion is that there are not enough of them. It would have been better if there were at least fifty questions in a sample exam, or two exams with at least fifty. When providing study questions, overkill is difficult to impossible to achieve, and eighteen is nowhere near that lofty goal.

I just took and passed the the test today and read this book cover to cover twice. I think it is a great book, but it seemed that the book's questions were a lot harder then the exams.

Coming from "The PHP Company", I fully expected this book to be "up-to-snuff" on everything it covered. I was sadly mistaken.

I barely made it past the third page of the first chapter, and I had to shelf it. The technical errors, the grammatical errors (I know, I'm not perfect), and the cheesey analogies all made it a very uncomfortable experience.

As another reviewer mentioned, this book needs to be updated to reflect the errata and such. I'm very displeased with it, and I will be sharing my opinion with Zend.

I don't regret getting this book, because I passed. It was a good *refresher* on some topics I don't normally script with (like file resources), but it was by no means the ticket to passing the exam. I'm not writing a gleaming review because I think it's easily possible to pass the exam, never having read this book *if* you're actually experienced with PHP.

Chances are, if you're taking the exam because you want to have a certification to go with your experience, you probably won't get much from this book (think review). If you don't consider yourself an expert, and you're taking the exam, this book won't make you pass, even if you memorize every word on every page.

I'm actually kind of glad this book took the middle road between complete PHP teaching and total crap since I think it probably helps keep the certification more pure for people who actually have experience to get certified. Read through the exam topics on the Zend website. If you think there's an area you're weak on, the book will probably help you realize what you might want to review in the PHP manual.

The "Zend PHP Certification Study Guide" is the perfect book for those wanting to take, and pass the "Zend PHP Certification Exam".

Relatively new to PHP myself, I found the majority of this book useful. With a "Terms You'll Need To Understand" and a "Techniques You'll Need To Master" section at the start of each chapter, the areas you are expected to know for the exam is explained. Also, with "Exam Prep Questions" at the end of each chapter, you are given a chance to put what you've just learned into practice.

Although it covers the basics, I would not recommend this to anyone wanting to learn PHP. The book, as stated in the Introduction "...is not a PHP development tutorial or a reference book on the language and its extensions.", so those with no experience in PHP that are looking to take the exam should seek to learn the basics elsewhere before buying this book.

Wanting to take the exam doesn't have to be the only reason to purchase this book. It serves as a useful reminder to those out of practice, and may even teach you a few new things you've yet to discover about PHP. There is no doubt however, that this guide is invaluable to those looking to get certified. And written by those who write the exam questions, who's to argue with that?

I purchased this book because it was supposed to be a study guide for a certification test. From what i have seen this book is filled with typo's and error that have been corrected in the errata. Not only that but i have talked to people whom have read the guide and taken the test and they said there were things on the exam that were never covered in the book.

This book will really help get your mind geared toward the exam, but don't think that you'll be ready just by reading this book. The breakdown of topics by chapter are a great way to get familiar with the exam subjects. I read every word on every page about 3 times, and while it helped for the test, it wasn't 100% inclusive of the material you'll be expected to know. Get the practice exam book, and spend some serious time with the relevant sections of the php manual online, writing code trying out questions you don't understand/ got wrong, and going through the php-recommended.ini file that is distributed with PHP 4.*. Of course, programming experience will be helpful, but many of the subjects are in areas that you might not used on a daily basis, especially to the knowledge level you'll need for the exam.

Good luck!

This book albeit different from what I was expecting, did live up to other expectations that I had prior to reading. I was expecting a high quality, in-depth book that was written by those with real php knowledge, as well as some examples of snippets in action. These were fulfilled, with Zend PHP Certification having very in-depth chapters, relative to the sections which are covered in the "PHP Exam."

Zend PHP Certification is as its title suggests; it is a practice guide for the "PHP Exam" not a guide for those who are new to php. It is a thorough guide to php, starting a chapter with the basics, then moving up to the advanced scripts which can be compiled using that code. I believe it is a must for those serious about their php coding.

I believe some areas of the book could have done with more explanation, but this in its rights, maybe because I am still relatively new to php.

Zend PHP Certification is a great guide and once again, I strongly recommend it to those who are serious about, or want to take their php seriously.

I got the second not the first edition of this book, so at least some of the errors have been corrected. And I agree with what the other reviewers said, this is certainly NOT the book to learn PHP from. I've been using PHP extensively for four years and I thought I might go for the cert.

What this book will provide you is a list of topics to know. But it fails to fill in the details, which are precisely what I forget in areas of development that I haven't been hanging out in lately.

And I just can't believe that the certification exam questions are really that easy.

If you buy the first edition of this book (August 2004), you should be aware that the publisher has released a list of errors (and they are many.) The errarta can be found at the publisher's website.

I've been using php since 1998 and now php software development is the primary focus of my business. This book is written by many well known experienced php developers and is a study guide for the php certification test which is also written by many of the same authors.

Because of the php knowledge held by the authors, I expected it to be fairly in depth and accurate and perhaps it could teach me a few odd things. At the same time I wanted to see if this PHP certification was something I should be looking for when my business hires future php developers.

I have to give this book the lowest rating available simply because it is so ridiculously riddled with mistakes. I expect technical books to have a few errors in them but I was often finding one or more errors on every page. Barely into the 4th chapter I tossed the book out when not only did they have a mistaken output code but now they went on to explain why it printed out that output even though php could of never given that output from their example code (regardless of version).

If it was just the type or cut 'n paste type errors I would of over looked them and knocked my review only down to two stars but to see them describing something that is incorrect php behaviour (they do it right in the very next sentence for a different section of the same example so they know the behaviour, but why would they describe it wrong in an earlier section of the same example)

These developers do know php well so I am stumped at the poor quality of this book. I'm wondering if this thing even proof read or just translated from another language by non-programmers?

Some people will want to know the errors and there are too many to list them all but an example of small errors is the very first chapter ends with 3 exam prep questions of which 2 have errors in the ending descriptions as to why an answer is right. The first one has the line "(the remainder of the division of 5 by 2)" when it should be 5 by 3. The third question in the description says increment instead of decrement.

These two examples of mistakes are small however and only annoying though most of these should of been easily caught. Where I lost faith in the technical aspects of the book was at the beginning of chapter 4.

Here they start to describing how php handles array keys. They start with example code along with the output code from the example code and then go on to describe how php behaves in a specific situation (converting "numerical" string keys into integers). Their output code printed is wrong as the very first key would of been an integer and not a string as they printed it.

I figured this was just another small mistake but then they go on in the description as to why it outputs this code taking you through each key. The first key they again say it will keep the string value of "1" as the key (which is wrong). Then in the very next sentence they explain why the second key is converted from a string to an integer because of one of php's behaviours to convert numeric strings to integers (though they left out that this behaviour only happens to the keys when you are creating arrays, not the values). This means they know this behaviour but obviously missed it in the first key as it was also a numeric string and would of been converted to an integer as well.

It was obvious they wrote the output code by hand rather than actually running it and in doing so made a mistake in it which could of been easily prevented. What bothered me is that they then go on and describe why it output this code, even though php could not of output this code from their example. It is as if the writer of this section didn't know why the first key came out as a string so they just repeated as they were in a hurry to show the second key as their big example of insight missing the fact the first key they rushed over should of been the exact same example.

After seeing this level of lack of attention to detail spent in this book I lost all respect for the book. I also lost faith in the level of detail the same authors would of put into their Zend PHP Certification test.

With the book being my only guide to the quality of the certification test, as an owner of a software development business I will NOT put applicants for php programmers that have Zend PHP certification above any other applicant until I have reason to believe otherwise.

The current edition of my book I would not even give away but all is not lost as I have already found a good use for it. When hiring other php developers I will give this book to an applicant during an interview and let them read any two random pages and have them tell me where the mistakes are in the code or descriptions of the code. If they know php well enough to quickly see these types of errors, then this is perhaps the best test of all to see their deeper understanding of php.

Sun, Oracle and other companies offer certification of skills in their products. Now, Zend Technologies seeks to do likewise with PHP programming. The twist being that here, they do not own PHP. But along with their exams, they offer this slim book.

It expects you to already have been coding in PHP. If this applies to you, then you should find the book a breeze. Each chapter gives a synopsis of an aspect of PHP. Followed by 5 or 6 questions on it. The questions are of moderate difficulty. Mostly mutiple choice. Which probably reflects the format of most questions on the actual exams. There is an occasional question which might require you to design or write code.

What I am unclear about is how well known Zend is. For Sun and Oracle, who certify in their proprietary products, there is a natural home base advantage to doing so, that many others can recognise. If you want to get some certification in PHP, you need to check around to see if you'd consider that Zend is sufficiently credible for you to invest in the exam [and this book].

Let's be blunt, Assume you are hiring someone to oversee your PHP system and have it narrowed down to two candidates. One of the candidates says, "Oh yeah, I know all about PHP." The other candidate says, "Oh yeah, I know all about PHP, I've passed the Zend certification exam." Your next question is likely to be "What's Zend Certification?" And the job candidate says, "A PHP specialist company, you can learn more about them at zend.com." After that, all other things being equal, the certified candidate is the one you're likely to hire.

This book is not the one I'd pick to learn PHP. There are others better suited. But to pass the Zend certification exam, this is the one. It tells you specifically what you need to know, has a sample exam and doesn't cost very much. What more can you want?

This book is filled with errors so it is not a good book for learning PHP, but that is not it's purpose. If you have experience coding PHP this book will give you a good overview of topics that may appear on the Zend Certification Exam and a good indication of subjects you may need to study further. Good Luck!
