What is Yii 2 ? Please Explain?

Yii is a component-based PHP framework that has a very high performance and is used for developing modern web applications at a faster pace. The name Yii is a shortened version of the word ‘yes’.

Yii2 is the second version of the application that inherited the simple, fast and yet highly extensive PHP framework. The features of the Yii2 are multi-tier caching support, pagination, session’s storage in a database, theming, et cetera.

This is very helpful
