Code quality tools

A few other tools have been added to ensure code quality (to a certain degree).

PHP Coding Standards Fixer

The PHP Coding Standards Fixer (PHP CS Fixer) tool fixes your code to follow standards; whether you want to follow PHP coding standards as defined in the PSR-1, PSR-2, etc., or other community driven ones like the Symfony one. You can also define your (team's) style through configuration.

You can run the fixer by executing

docker-compose run --rm php-cli composer lint:fix

The configuration is stored in ./.php-cs-fixer.dist.php

PHPStan

PHPStan scans your whole codebase and looks for both obvious & tricky bugs. Even in those rarely executed if statements that certainly aren't covered by tests. You can run it on your machine and in CI to prevent those bugs ever reaching your customers in production.

You can run PHPStan by executing

docker-compose run --rm php-cli composer phpstan:run

The configuration is stored in ./phpstan.neon

To generate a new baseline, run

docker-compose run --rm php-cli composer phpstan:generate-baseline
