TheCodingMachine's additional rules for PHPStan

This package contains a set of rules to be added to the wonderful PHPStan static analyzer.

Those rules come from TheCodingMachine best practices. They are more "strict" than the default PHPStan rules and some may be controversial. We use those at TheCodingMachine, have found them to help us in our daily work, and ask anyone working with us to follow them.

Rules list

Exception related rules

Type-hinting related rules

This is a PHP 7.1+ rule:

  • You should use type-hinting when possible
  • If not possible, you should use a Docblock to specify the type
  • If type-hinting against an array, you should use a Docblock to further explain the content of the array

Superglobal related rules

Condition related rules


// Never use public properties
// Never use globals


We assume that PHPStan is already installed in your project.

To use this extension, require it in Composer:

composer require --dev thecodingmachine/phpstan-strict-rules

If you also install phpstan/extension-installer then you're all set!

Manual installation

If you don't want to use phpstan/extension-installer, include phpstan-strict-rules.neon in your project's PHPStan config:

    - vendor/thecodingmachine/phpstan-strict-rules/phpstan-strict-rules.neon
