PSR-12 standard release

[razvanphp]

Since Yii2 mostly follows the new extended rules, can we have a new release tag that enforces this standard?

It would help the community and junior developers follow the rules.

Thank you!

Could be done but needs work. Do you have some time for a pull request?

[razvanphp]

Sorry, you mean work for this repo only or to adjust also the framework code to pass all the new checks?

[samdark]

This repo only first.
