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.

Chapter 6. Adapting to MVC

Web applications are more complex than what we have built so far. The more functionality you add, the more difficult the code is to maintain and understand. It is for this reason that structuring your code in an organized way is crucial. You could design your own structure, but as with OOP, there already exist some design patterns that try to solve this problem.

MVC (model-view-controller) has been the favorite pattern for web developers. It helps us separate the different parts of a web application, leaving the code easy to understand even for beginners. We will try to refactor our bookstore example to use the MVC pattern, and you will realize how quickly you can add new functionality after that.

In this chapter, you will learn the following:

  • Using Composer to manage dependencies
  • Designing a router for your application
  • Organizing your code into models, views, and controllers
  • Twig as the template engine
  • Dependency injection
