The PostForm model is used to validate the form data. If the data is valid, a new Post record is created and saved to the database. Package library: Yii provides a validation library that includes data validation rules and error messages handling. Overall, Yii provides a robust set of libraries for web development, including a database access layer, authentication and authorization, validation rules, URL routing, caching, and many others. Its easy-to-use features and efficiency in web development have made it a popular choice for building applications.
