Yii is a high-performance PHP framework that is designed to be efficient and flexible. It follows the Model-View-Controller (MVC) architectural pattern and provides a robust set of features for developing web applications. Yii2 is the latest version of the framework, which builds upon the success of its predecessor Yii.
Some key features of Yii2 include:
High performance: Yii2 is known for its high performance due to its efficient caching and lazy loading mechanisms. It also provides support for various caching systems such as Memcached and Redis.

Database support: Yii2 supports a wide range of databases, including MySQL, PostgreSQL, SQLite, and Oracle. It provides an intuitive database query builder and ActiveRecord, which simplifies database operations and makes them more efficient.
RESTful API development: Yii2 has built-in support for RESTful API development. It provides a set of tools and conventions to easily create APIs that follow the REST architectural style.
Internationalization and localization: Yii2 supports internationalization and localization out of the box. It provides tools for translating messages, formatting dates and numbers, and handling multilingual content.
Testing: Yii2 has built-in support for unit testing and functional testing. It provides a testing framework that makes it easy to write and run tests for your application.
Overall, Yii2 is a powerful and feature-rich PHP framework that simplifies the development of web applications. It provides a solid foundation for building scalable and efficient applications, and its extensive documentation and active community make it a popular choice among PHP developers.
