Build a RESTful API using PHP and Yii2

This tutorial demonstrates the creation of a RESTful API using PHP and the Yii2 framework. The application is built to manage library resources, specifically members and books, with basic CRUD operations and loan-related functionality. The API uses Yii's Active Record classes for models, controllers, and routing, providing an object-oriented approach to database interactions and API endpoints. The application includes security features such as CSRF validation and secure-by-default configuration. The codebase is generated using the Yii framework's built-in tools, including the GII (Generator for Interface) tool, which simplifies the creation of models, controllers, and other components. The tutorial covers topics such as database setup, model creation, controller implementation, routing, and API testing, providing a comprehensive overview of building a RESTful API with Yii2.
