Yii is a high-performance PHP framework used for developing web applications. It’s an open-source framework that follows the MVC (Model-View-Controller) architectural pattern, which helps in organizing code and separating concerns.

Features of Yii Framework:

High Performance:

Yii is known for its high performance. It is built with performance optimization in mind and utilizes caching mechanisms, lazy loading, and other techniques to ensure fast execution.

Security:

Yii provides built-in security features such as input validation, output filtering, SQL injection prevention, and cross-site scripting (XSS) prevention to help developers build secure applications.

Code Generation Tools:

Yii comes with powerful code generation tools that automate the process of creating models, controllers, forms, and CRUD (Create, Read, Update, Delete) operations, thereby saving development time.

Database Access Object (DAO) and Object-Relational Mapping (ORM):

Yii provides both DAO and ORM support for database operations. Developers can use either approach based on their preferences and project requirements.

RESTful API Development:

Yii makes it easy to build RESTful APIs by providing built-in support for RESTful routing, request parsing, and response formatting.

Community Support:

Yii has an active and supportive community of developers who contribute to the framework’s development, provide assistance on forums, and share tutorials and resources.
