Who this book is for
This book is for anyone who wishes to write web applications with PHP. You do not need to be a computer science graduate in order to understand it. In fact, we will assume that you have no knowledge at all of software development, neither with PHP nor with any other language. We will start from the very beginning so that everybody can follow the book.
Experienced readers can still take advantage of the book. You can quickly review the first chapter in order to discover the new features PHP 7 comes with, and then focus on the chapters that might interest you. You do not need to read the book from start to end, but instead keep it as a guide, in order to refresh specific topics whenever they are needed.
