## What it is
Yii 1.1.x is a high-performance, component-based PHP web framework for building web applications using an MVC architecture. It has reached end of life and now only receives security fixes and PHP 7/8 compatibility updates.

## Use cases
- maintain a legacy Yii 1.1 application
- keep an old Yii app running on PHP 8
- scaffold a classic PHP MVC web application
- upgrade PHP version on a server hosting a Yii 1.1 app
- apply security patches to a Yii 1.1 codebase

## When to choose
- you are maintaining an existing Yii 1.1 application
- you need PHP 7/8 compatibility fixes for a legacy Yii project
- you want a mature, well-documented PHP framework for an old codebase

## When to avoid
- you are starting a new project - use Yii 2 or Yii 3 instead
- you need modern framework features or long-term community support
- you want a framework with active feature development

## Facets
- artifact type: framework
- maturity: maintenance
- function: web-framework, orm, templating, routing, auth, cli
- domain: web-development, backend, developer-tools
- platform: php, windows, cli
- tags: yii1, php-framework, mvc, legacy, rapid-development, linux, macos, web-server
