Overview of this book

Yii is a free, open source web application development framework written in PHP5 that promotes clean DRY design and encourages rapid development. It works to streamline your application development time and helps to ensure an extremely efficient, extensible, and maintainable end product. Being extremely performance optimized, Yii is a perfect choice for any size project. However, it has been built with sophisticated, enterprise applications in mind. You have full control over the configuration from head-to-toe (presentation-to-persistence) to conform to your enterprise development guidelines. It comes packaged with tools to help test and debug your application, and has clear and comprehensive documentation. This book is a collection of Yii2 recipes. Each recipe is represented as a full and independent item, which showcases solutions from real web-applications. So you can easily reproduce them in your environment and learn Yii2 fast and without tears. All recipes are explained with step-by-step code examples and clear screenshots. Yii2 is like a suit that looks great off the rack, but is also very easy to tailor to fit your needs. Virtually every component of the framework is extensible. This book will show how to use official extensions, extend any component, or write a new one. This book will help you create modern web applications quickly, and make sure they perform well using examples and business logic from real life. You will deal with the Yii command line, migrations, and assets. You will learn about role-based access, security, and deployment. We’ll show you how to easily get started, configure your environment, and be ready to write web applications efficiently and quickly.

Following best practices

In this recipe, you will see how to configure Yii2 for the best performance and some additional principles of building responsive applications. These principles are both general and Yii-related. Therefore, we will be able to apply some of these even without using Yii2.

Getting ready

Create a new yii2-app-basic application using the Composer package manager, as described in the official guide at http://www.yiiframework.com/doc-2.0/guidestart-installation.html.

How to do it…

  1. Update your PHP to the latest stable version. Major releases of PHP may bring significant performance improvements. Turn off the debug mode and set the prod environment. This can be done by editing web/index.php as follows:

    defined('YII_DEBUG') or define('YII_DEBUG', false);
defined('YII_ENV') or define('YII_ENV', 'prod');

    Note

    Note: In the yii2-app-advanced application skeleton, you can use the shell command php init and opt production environment for loading optimized index.php and configuration files...
