TLint for enforcing a particular "Laravel-style" https://github.com/tighten/tlint
PHP CS Fixer to enforce consistent code style and PSR-12 (+ extensions, such as Symfony's) https://github.com/FriendsOfPHP/PHP-CS-Fixer
Larastan to eliminate silly bugs https://github.com/nunomaduro/larastan
You can set up Git pre-commit hooks to automatically run php-cs-fixer for example. That way, it is always consistent. You can use GrumPHP for this, but I personally use husky & lint-staged.
TLint does not support passing multiple files through its CLI, so I'm probably going to submit a PR to support that (tools like lint-staged depend on that). If you have a CI environment, it is best to also run Larastan in your pipeline.
