@kkmuffme Please dont do unrelated changes and code style changes.

Please dont do unrelated changes and code style changes.

Thanks for the comment - the CI reports those unrelated code style issues as errors though, that's why I fixed them. I'll just leave those phpcs reported CI issues that are outside of my changes there then (and the CI fail)

The failing, existing test is bc that test was already wrong beforehand and led to a fatal error in PHP <8, since "static" type is only available since PHP 8+
I didn't find how you handle tests that are version specific, please let me know, otherwise just remove that existing "static" test.

I think it also might make sense for the CI to actually use strict types on the test templates and use php -l linting to catch tests that will result in fatal errors.
