FOREWORD BY ANDI GUTMANS
There are many advantages to having a PHP certification program. Foremost, it allows employers, especially those of the non-technical kind, to set a certain standard for their PHP hiring decisions; theyll know that people who are certified have passed a set of hurdles in earning their credentials and can clearly demonstrate their knowledge of PHP and its related technologies. Not only does that mean that a Zend Certified Engineer will automatically match such criteria and have an immediate advantage on the job market, but the certification process also allows for more and more enterprises to adopt PHP. This, in turn, will lead to a much more vibrant job market for PHP developersmaking it easier to make a living from what PHP developers like doing most. I have no doubt that we will see an increase in the ongoing PHP proliferation due to the existence of Zends PHP Certification Exam. A few weeks ago, I finally found time to take the Zend PHP Certification Exam. Despite having written some of the questions and being part of the exam education advisory board that reviewed the questions a few months ago, I was surprised to realize that I was a tad bit tenseI think not only because exams in general tend to have this effect on me, but also because I remembered that the questions were very thorough, most probably due to the fact that the exam authors themselves are leaders in the PHP community who wanted to come up with the best possible questions. Without making the exam overly difficult, this ensured that every question was well-thought-out, thoroughly peer-reviewed and carefully constructed; this is bound to make any prospective exam-takerespecially one that was an integral part of such a thorough processa bit nervous! Im happy to say that I passed the exambut I admit that some questions were quite hard. I think that, overall, the exam is fair but, unlike many other certification tests, much more thorough. A PHP developer with no experience really cannot pass this exam, which I think is great. It really certifies PHP developers who have experience in developing PHP based web applications in the real world. I believe this book will be of great help in preparing for the certification exam. Both Marco and John were on the Zend PHP Certification Advisory Board and understand the nature of the exam and what its goals are. Both authors also have many years of experience in PHP, which is readily recognizable from the books contents. This book very nicely covers the different topics on which you will be tested and provides questions that are very similar to the ones you will see on the exam. Having the answers at the end of each chapter will make it easy for you to validate your strengths and weaknesses. I wish you all the best with the certification progress and hope you will soon join the growing family of Zend Certified Engineers.
