Is there any chance to use slim2 with php8.1?

Hi, this is not really an issue, just a question.

I need to update php version to php 8.1 in my webserver but I still have an old slim2 application.
Is there any way to use it with php8?

I tried to run it and I'm facing many fatal errors due to Return type of ArrayAccess mainly in slim\Slim\Middleware\Flash.php and slim\Slim\Helper\Set.php

Thank you for any idea (other than full app refactor :-D )

Roughly, you need to adopt it into your project and update the code appropriately.

@tobiascapin , how about giving Rector a try?
