The question facing PHP developers these days is not "Should I use the new features?", but "How do I implement these features to build better applications faster?" I remember building applications in PHP 4. It was a simpler time for PHP developers as it could be intermingled with HTML and everything was in one file. Instead of frameworks, we had libraries of functions that got included. Applications were basically just CRUD desktop applications that we figured out how to shovel onto the web. Application development has changed several times since then. New frameworks, such as AJAX, PHPUnit, composer, and API-First, were introduced. All of these things, and many others, have influenced how PHP developers build applications. Today, you will be laughed out of a job if you have a paged-based application that mixed HTML and PHP. So, what will you do? How will you build modern PHP applications and APIs? How will you leverage all the new tools that PHP gives you to build faster, better, stronger applications? I am so glad you asked. My friend Doug Bierer has the answer for you. This isn't YAUT (Yet Another Useless Tome) of information that you will put on a shelf and never use. The book you are holding in your hands is destined to, quickly, be a part of your ducktape library. (Every developer has a ducktape library. It is made up of those books you refer to so often that they are now held together by ducktape.) Doug takes the time to show you the new features that you need to understand, like so many developer books out there. Where this book is different is that the author takes the time to show you how to solve real-world problems using these new tools. Not only do you learn, but you can immediately solve problems with what you learn. [ FM-5 ] You don't have to be an expert in PHP to use advanced concepts. However, you do have to learn, understand, and use these advanced concepts if you ever hope to grow as a programmer. This book will help you down your path to becoming a better programmer. Cal Evans Nomad PHP Nerd Herder for the World Wide Herd [ FM-6 ] About the Author Doug Bierer has been hooked on computers since his first program, written in Dartmouth BASIC on a DEC PDP-8, in 1971. In his wide-ranging career, this author has been a professional contract programmer since 1978, having written applications in BASIC, PL/I, assembler, FORTH, C, C++, dBase/FoxBase/Clipper, Pascal, Perl, Java, and PHP. He deployed his first website in 1993 while living in San Francisco. He speaks four languages, has traveled extensively, and has lived in the USA, France, the Netherlands, England, Sweden, Scotland, and Thailand. He also spent some years doing Linux system administration and TCP/IP networking. He is also an accomplished musician (he has written over 60 songs) as well as a writer, under the pen name of Douglas Alan. Doug's own company is unlikelysource.com, which specializes in consulting, PHP programming, website development, and training (primarily for Zend Technologies Ltd and Rogue Wave Software Inc. His works of fiction published on https://www.lulu.com/ are The End, And Then? and Further Indications. Some of his technical works for O'Reilly Media are Learning PHP and MySQL, Learning PHP Security, Learning MongoDB, and Learning Doctrine. First and foremost, I would like to dedicate this book to my mother, Betty Bierer, who passed away in May 2016. She encouraged me all my life, and applauded my accomplishments (no matter how bad!). She attended all my music concerts, bought all my CDs, and read all my books (even if she did not understand them). I would also like to thank my long-suffering wife, Siri, who patiently endured the hours it took me to write this book without complaint. (She did, however, make threats if I agreed to take on another one... negotiations are ongoing.) Finally, I would like to thank a number of notables in the PHP community who let me bounce ideas off them or offered inspiration. These include, Matthew Weir O'Phinney, Cal Evans, Daryl Wood, Susie Pollock, Salvatore Pappalardo, Slavey Karadzhov, and Clark Everetts. [ FM-7 ] About the Reviewers Salvatore Pappalardo, a tech geek from birth, has been a software engineer since 2002. He loves "from scratch" development.
