Features of Yii2 Framework

• Namespace: One of the most evident features of Yii2 is the use of Namespaces. All the core classes of Yii2 are namespaced and class names are not preceded by "C". The use of Namespace dismisses the possibility of the code being vague in class names. The Yii class loader enables developers to use any core class of Yii without explicitly including that class file.
• Component and Object: The  Component class CComponent in Yii1.1 is now enhanced and split into two further classes - Object Class and Component Class, in the newly designed Yii2 framework. Object Class stores the basic data structures and Component Class extends from it adding events and behaviors.
• Object Configuration: Yii2 offers a simplified and uniform way of configuring objects.
• Event: The events no longer need an on-method since the developers can use any event names and attach a handler to the event.
• Path Alias: Path Alias is extended to both file/directory paths and URLs. It is also closely related with Namespaces.
• View: A View class is introduced in Yii2 to represent the view part of the MVC pattern. Its "view" application component enables developers to globally configure it. Developers can have access to it through any view file via $this.
• Assets: A new concept is introduced in Yii2 called asset bundle that is similar to script packages in Yii1.1 only with better configuration and support.

• Faster development: The projects involving repetitive tasks take a lot of unnecessary time. Yii2 offers a number of tools to customize those tasks and saves your precious time. It allows you to quickly create code templates for Forms, Extensions, and Models, etc.
• Yii2 vs Laravel: This fast-moving technological world requires upgraded tools and techniques regularly to keep pace with the modernization and advancement. To keep up with this need, several PHP full-stacked PHP frameworks are introduced for the development of massive projects. However, among all those frameworks, Yii2 and Laravel are the two most popular and used frameworks. Both of these have proven to be convenient and effective for the developers but Yii2 exceeds in popularity due to its impressive features and outstanding performance. Also, Yii2 offers ease of development to the engineers with its simple configuration. Though Laravel too has exhibited excellent properties but Yii2 has slightly outdone Laravel in the following aspects:
• Extensions provided by Yii2 are incompetent as compared to any other PHP frameworks
• Yii2 web development is safer than Laravel since it provides advanced security tools.
