Sniffs for PHP_CodeSniffer by Max Antipin

composer require --dev max-antipin/php-code-sniffs

Development & testing

Start a dev container and install dependencies:

make up

Enter the dev container:

make shell

Run all tests:

make test-all

Run all tests without creating one more service:

PHP_VERSION=8.3 docker compose -f .docker/compose.yaml run --rm --build --quiet-build -e XDEBUG_MODE=off php-dev make test-all

Run service with test coverage:

docker compose -f .docker/compose.yaml up dev-coverage

The results will be stored in var/coverage-report/.

Below PHP 8.4 there is a conflict between PHP_CodeSniffer and nikic/php-parser which causes fatal error: Token T_PUBLIC_SET has ID of type string, should be int. You may be using a library with broken token emulation. nikic/php-parser package is used by PHPUnit while calculation code coverage.

PHP_CodeSniffer file src/Util/Tokens.php, lines 183-194:
