What is Yii PHP Framework?

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

Yii is very easy to learn and use. You only need to know PHP and object-oriented programming. You are not forced to learn a new configuration or templating language.

Yii is extremely fast. Its overhead to applications written on top of it is negligible. As a matter of fact, it is one of the most efficient PHP frameworks around.

Yii is purely object-oriented. Yii is highly reusable and extensible. Everything in Yii is a self-contained component which can be configured, reused or extended easily.
