# Rector Rules for PHP Downgrade
See available [Downgrade rules](https://getrector.com/find-rule?query=downgrade+rules)
## Install
This package is already part of [rector/rector](http://github.com/rectorphp/rector) package, so it works out of the box.
All you need to do is install the main package, and you're good to go:
```bash
composer require rector/rector --dev
```
## Use Sets
To add a set to your config, use `Rector\Set\ValueObject\DowngradeLevelSetList` class and pick target set:
```php
use Rector\Set\ValueObject\DowngradeLevelSetList;
use Rector\Config\RectorConfig;
return static function (RectorConfig $rectorConfig): void {
$rectorConfig->sets([
DowngradeLevelSetList::DOWN_TO_PHP_72
]);
};
```
Then run Rector to downgrade your code to PHP 7.2!
```bash
vendor/bin/rector
```
## How the Downgrade Workflow looks?
It's simple in the nature. Read these *how-to* posts to get the idea:
* [How all Frameworks can Bump to PHP 8.1 and You can Keep Using Older PHP](https://getrector.com/blog/how-all-frameworks-can-bump-to-php-81-and-you-can-use-older-php)
* [Introducing ECS Prefixed and Downgraded to PHP 7.1](https://tomasvotruba.com/blog/introducing-ecs-prefixed-and-downgraded-to-php-71/)

## Learn Rector Faster
Rector is a tool that [we develop](https://getrector.com/) and share for free, so anyone can save hundreds of hours on refactoring. But not everyone has time to understand Rector and AST complexity. You have 2 ways to speed this process up:
* read a book - The Power of Automated Refactoring
* hire our experienced team to improve your code base
Both ways support us to and improve Rector in sustainable way by learning from practical projects.
