Built on PHPStan, this static analysis tool will check for correctness (e.g. using a class that doesn't exist), deprecation errors, and more.

Why? While there are many static analysis tools out there, none of them run with the Drupal context in mind. This allows checking contrib modules for deprecation errors thrown by core.

Are you ready for Drupal 9? Check out our Drupal 9 Readiness instructions for details on how this tool can help.

You can install this in your project using Composer as a development dependency like so:

composer require mglaman/drupal-check --dev

You can also install this globally using Composer like so:

composer global require mglaman/drupal-check

drupal-check:1.4.0 set PHPStan's analysis level to 2 for deprecations and 6 for analysis. This ensures basic analysis errors are fixed to provide the best deprecated code detection experience. You can read more about PHPStan's rule levels here: https://phpstan.org/user-guide/rule-levels

If you do not want to run PHPStan at level 2 and only report deprecation messages, use the following instructions

composer remove mglaman/drupal-check
composer require  --dev phpstan/phpstan \
  phpstan/extension-installer \
  mglaman/phpstan-drupal \
  phpstan/phpstan-deprecation-rules

Create a phpstan.neon file with the following:

parameters:
	customRulesetUsed: true
	ignoreErrors:
		- '#\Drupal calls should be avoided in classes, use dependency injection instead#'
		- '#Plugin definitions cannot be altered.#'
		- '#Missing cache backend declaration for performance.#'
		- '#Plugin manager has cache backend specified but does not declare cache tags.#'

	# FROM mglaman/drupal-check/phpstan/base_config.neon
	reportUnmatchedIgnoredErrors: false
	excludePaths:
		- */tests/Drupal/Tests/Listeners/Legacy/*
		- */tests/fixtures/*.php
		- */settings*.php
		- */bower_components/*
		- */node_modules/*
