Set of rules for PHPStan used by Symplify projects


composer require symplify/phpstan-rules --dev

1. Add Static Rules to phpstan.neon

Some of rules here require configuration, some not. We recommend to start with rules that do not require any configuration, because there is just one way to use them:

# phpstan.neon
    - vendor/symplify/phpstan-rules/config/static-rules.neon

Give it couple of days, before extending.

Some rules require extra services. To avoid service duplications, they're in the separate config that you can easily include:

    - vendor/symplify/phpstan-rules/config/services/services.neon

2. Pick from Prepared Sets

Do you know prepared sets from ECS or Rector? Bunch of rules in single set. We use the same approach here:

    - vendor/symplify/phpstan-rules/config/array-rules.neon
    - vendor/symplify/phpstan-rules/config/code-complexity-rules.neon
    - vendor/symplify/phpstan-rules/config/doctrine-rules.neon
    - vendor/symplify/phpstan-rules/config/naming-rules.neon
    - vendor/symplify/phpstan-rules/config/regex-rules.neon
    - vendor/symplify/phpstan-rules/config/forbidden-static-rules.neon
    - vendor/symplify/phpstan-rules/config/test-rules.neon

Pick what you need, drop the rest.

3. How we use Configurable Rules

Last but not least, configurable rules with saints defaults. That's just polite wording for opinionated, like AllowedExclusiveDependencyRule.

You might not like them, but maybe you do:

# phpstan.neon
    - vendor/symplify/phpstan-rules/config/configurable-rules.neon

Give it a trial run... so many erros and unclear feedback.... Would you like to configure them yourself? That's good! We use one rule by another in other projects too, instead of one big import.

  • Pick one and put it to your phpstan.neon manually.
  • Configure it to your specific needs and re-run PHPStan. It's easier to be responsible, when you're in control.

E.g. ForbiddenNodeRule:

        class: Symplify\PHPStanRules\Rules\ForbiddenNodeRule
        tags: [phpstan.rules.rule]
                - PhpParser\Node\Expr\Empty_
                - PhpParser\Node\Stmt\Switch_
                - PhpParser\Node\Expr\ErrorSuppress

You'll find them all in rules overview.

Happy coding!
