## What it is
Yii 2 is a high-performance, full-stack PHP framework for building modern web applications and APIs. It ships with an ORM (Active Record), MVC architecture, code generation tools, and sensible secure defaults out of the box.

## Use cases
- build a web application in php
- create a rest api with php
- rapid web development framework
- mvc framework with orm
- generate crud scaffolding for a database
- secure php framework with auth built in

## When to choose
- you want a batteries-included full-stack PHP framework with ORM, auth, and code generation
- you need fast performance and strong security defaults for a PHP web app or API
- your team already knows Yii or is upgrading from Yii 1.1

## When to avoid
- you prefer a micro-framework or minimal component set like Slim or Lumen
- you are starting a brand-new project and want the latest Yii 3 or another modern stack
- you need a non-PHP language or ecosystem
