In PHPStorm you can set up PHP > Quality Tools that will check your code as you code. This will help you write clean code. I suspect that most developers use a local configuration for these PHP > Quality Tools. But if you already have some Docker containers set up for your project, you should use the same PHP version and the same tool version, e.g. PHPStan, installed in this project via Composer. In this post I will guide you through the setup with many screenshots.
