## What it is
Rector is a PHP CLI tool that performs instant upgrades and automated refactoring of PHP codebases using AST-based rules. It supports upgrades from PHP 5.3 to 8.5 and framework migrations for projects like Symfony, PHPUnit, and Doctrine.

## Use cases
- upgrade php codebase to php 8
- automatically migrate symfony framework version
- refactor legacy php code automatically
- run automated code quality checks in ci
- upgrade phpunit tests to latest version
- modernize legacy php 5.3 application

## When to choose
- you need to upgrade PHP or framework versions with minimal manual effort
- you want continuous automated refactoring in CI to maintain code quality
- you maintain a large legacy PHP codebase that needs modernization

## When to avoid
- your project is not written in PHP
- you need one-off manual refactoring with full human control over every change
- your codebase is untyped procedural code with no OOP structure, where Rector works less effectively
