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
• 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.
