Install
This package is already part of rector/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:
composer require rector/rector --dev
Use Sets
To add a set to your config, use Rector\Set\ValueObject\DowngradeLevelSetList
class and pick target set:
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!

Learn Rector Faster
Rector is a tool that we develop 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

Both ways support us to and improve Rector in sustainable way by learning from practical projects.
