Overview of this book

PHP is a great language for building web applications. It is essentially a server-side scripting language that is also used for general purpose programming. PHP 7 is the latest version with a host of new features, and it provides major backwards-compatibility breaks. This book begins with the fundamentals of PHP programming by covering the basic concepts such as variables, functions, class, and objects. You will set up PHP server on your machine and learn to read and write procedural PHP code. After getting an understanding of OOP as a paradigm, you will execute MySQL queries on your database. Moving on, you will find out how to use MVC to create applications from scratch and add tests. Then, you will build REST APIs and perform behavioral tests on your applications. By the end of the book, you will have the skills required to read and write files, debug, test, and work with MySQL.

PHP in web applications


Even though the main purpose of this chapter is to show you the basics of PHP, doing it in a reference-manual kind of a way is not interesting enough, and if we were to copy-paste what the official documentation says, you might as well go there and read it by yourself. Keeping in mind the main purpose of this book and your main goal is to write web applications with PHP, let us show you how to apply everything you are learning as soon as possible, before you get too bored.

In order to do that, we will now start on a journey towards building an online bookstore. At the very beginning, you might not see the usefulness of it, but that is just because we've still not shown all that PHP can do.
