Yii is among the oldest PHP frameworks and has come up with its latest version Yii 2 to get a much-needed popularity boost. Yii 2 is purely object-oriented and is based on the DRY (Don’t Repeat Yourself) coding concept. One Yii 2 strong feature is the lazy loading technique, which makes it faster compared to other frameworks. It excels for large-scale website development because it can be integrated with AJAX and JQuery features. Additionally, it has a powerful class code generator called Gii that facilitates object-oriented programming and rapid prototyping to provide a web-based interface that allows you to interactively generate the code you need.
