GitHub - symplify/coding-standard: Coding Standard rules for PHP projects with focus on Clean Architecture

Downloads

Coding standard rules for clean, consistent, and readable PHP code. No configuration needed—just install and let it handle the rest.

They run best with ECS.

Install

composer require symplify/coding-standard --dev
composer require phpecs/phpecs --dev
  1. Register in ECS config:
 # ecs.php
 use Symplify\EasyCodingStandard\Config\ECSConfig;
 use Symplify\EasyCodingStandard\ValueObject\Set\SetList;

 return ECSConfig::configure()
     ->withSets([SetList::SYMPLIFY]);
  1. And run:
# dry-run without changes
vendor/bin/ecs


# apply changes
vendor/bin/ecs --fix
