What are the advantages and disadvantages of YII2 framework

YII2 framework introduction:

yii is a high-performance component-based PHP framework for developing large-scale Web applications. Yii is written in strict OOP and has complete library references and comprehensive tutorials.

Yii has two main versions: Yii1.1 and Yii2.0. Yii1.1 is an old version, and no new development is being carried out now. The official is only carrying out maintenance, updating security vulnerabilities, etc., and will not introduce new features.

Yii2.0 is a framework that is completely rewritten based on Yii1.1. It absorbs many of the latest technologies and mainstream conventions in development, and is the representative of the latest generation of Web development frameworks.

Uses new technologies and standards such as PHP namespace, Trait, PSR standard, Composer and Bower package manager.

Implemented new architecture and new modes such as dependency injection, dependency injection container and service locator (Service Locator).

Yii2.0 attaches great importance to security and adopts a series of measures to effectively prevent SQL injection, XSS attacks, CSRF attacks, cookie tampering, etc.

Provides Yii debugging toolbar, Gii code generator and document generator and other efficient development tools for hard-working coders.

Integrates Codeception and Faker, and combines with DB Migration to provide a fixture framework to facilitate test development.

Provides a simple application template and an advanced application template, which are suitable for different development scenarios and can help developers build their own applications as soon as possible.
