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.

Creating a REST API with Laravel

In this section, we will build a REST API with Laravel from scratch. This REST API will allow you to manage different clients at your bookstore, not only via the browser, but via the UI as well. You will be able to perform pretty much the same actions as before, that is, listing books, buying them, borrowing for free, and so on.

Once the REST API is done, you should remove all the business logic from the bookstore that you built during the previous chapters. The reason is that you should have one unique place where you can actually manipulate your databases and the REST API, and the rest of the applications, like the web one, should able to communicate with the REST API for managing data. In doing so, you will be able to create other applications for different platforms, like mobile apps, that will use the REST API too, and both the website and the mobile app will always be synchronized, since they will be using the same sources.

As with our previous Laravel...
