What is Yii

Yii is a high-performance component-based PHP framework for developing large-scale Web applications. It enables maximum reusability in Web programming and can significantly accelerate the development process. The name Yii (pronounced as Yee or [ji:]) stands for easy, efficient and extensible.

1. Requirements

To run an Yii-powered Web application, you need a Web server supporting PHP 5.1.0 or higher.

For developers who want to use Yii, understanding object-oriented programming (OOP) is very helpful, because Yii is a pure OOP framework.

2. What is Yii Best for?

Yii is a generic Web programming framework that can be used for developing virtually all sorts of Web applications. Because it is light-weighted and equipped with sophisticated caching solutions, it is especially suitable for developing high-traffic applications, such as portals, forums, content management systems (CMS), e-commerce systems, etc.

3. How is Yii Compared with Other Frameworks?

Like most PHP frameworks, Yii is an MVC framework.

Yii excels over other PHP frameworks in that it is efficient, feature-rich and clearly-documented. Yii is carefully designed from the beginning to fit for serious Web application development. It is neither a byproduct of some project nor a conglomerate of third-party work. It is the result of the authors' rich experience of Web application development and the investigation and reflection of the most popular Web programming frameworks and applications.
