Yii2 is a secure, quick, high-performance application/web-development framework created by Qiang Xue in 2008. Composer, a PHP dependency manager, is used by Yii to manage various requirements and installations (more on it later). Because of the lazy loading mechanism, Yii2 is also the quickest PHP framework.
jQuery integration is another excellent feature of Yii. The integration makes it easy for front-end developers to get started with the framework, and it generates code using scaffolding. Yii2, like Symfony, uses components to allow for quick application development.
