Overview of this book

Yii is a high-performance PHP framework best for developing Web 2.0 applications. It provides fast, secure, and professional features to create robust projects, however, this rapid development requires the ability to organize common tasks together to build a complete application. It's all too easy to get confused; this is where this book comes in. This book contains a series of practical project examples for developers starting from scratch. Each section contains the most relevant theories for every topic as you walk through developing each project, focusing on key aspects that commonly confuse users. The book starts with all the framework’s basic concepts, such as controllers and views, to introduce you to Yii and creating your first application, a simple news reader. You will be learn to configure URL rules to make a pretty URL, essential for search engine optimization. Next, you will walk through Model and ActiveRecord, key concepts in database interaction. The second application you will develop is a reservation system that allows you to manage rooms, customers, and reservations. For this, you will use database connection through SQL and ActiveRecord. More complex than the first one, this application will introduce you to the advanced template of Yii 2, splitting the app into two parts: a frontend for all visitors and a backend for the admin. Finally, you will move on to the last two applications: one that allows connections from remote clients, through RESTful components of Yii 2, and another that creates and organizes automatic tasks using the console application structure of Yii 2.

Chapter 13. Final Refactoring

This is the final stage of our development. Now that we have written all the working code, we must make it reusable but most importantly, maintainable. This chapter will help you to reuse code by means of widgets and other components. We will see some practical examples on how to use them. Then, we will deal with documentation, an important aspect of app development that allows everyone to quickly learn how a project is structured and built.

For the documentation, we are going to use the two most important tools provided by the framework in order to build API and guide references, making a real-life example. We will cover the following topics:

  • Creating widgets

    • Example – creating a widget with a carousel

  • Creating components

    • Example – creating a component that creates a backup of the MySQL database and sends an e-mail to the administrator

  • Creating modules

  • Generating the API documentation

    • Example – using API documentation to generate doc of the app
