Build Status CircleCI

Extension for PHPStan to allow analysis of Drupal code.

Usage

When you are using phpstan/extension-installer, phpstan.neon will be automatically included.

Otherwise add phpstan.neon to your Drupal project.

Make sure it has

includes:
	- vendor/mglaman/phpstan-drupal/extension.neon

Enabling rules one-by-one

If you don't want to start using all the available strict rules at once but only one or two, you can! Just don't include the whole rules.neon from this package in your configuration, but look at its contents and copy only the rules you want to your configuration under the services key:

services:
	-
		class: PHPStan\Rules\Drupal\PluginManager\PluginManagerSetsCacheBackendRule
		tags:
			- phpstan.rules.rule

Excluding tests from analysis

To exclude tests from analysis, add the following parameter

parameters:
	excludes_analyse:
		- *Test.php
		- *TestBase.php

Deprecation testing

Add the deprecation rules to your Drupal project's dependencies

composer require --dev phpstan/phpstan-deprecation-rules

Edit your phpstan.neon to look like the following:

includes:
	- vendor/mglaman/phpstan-drupal/extension.neon
	- vendor/phpstan/phpstan-deprecation-rules/rules.neon

To only handle deprecation testing, use a phpstan.neon like this:

parameters:
	customRulesetUsed: true
	reportUnmatchedIgnoredErrors: false
	# Ignore phpstan-drupal extension's rules.
	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.#'
includes:
	- vendor/mglaman/phpstan-drupal/extension.neon
	- vendor/phpstan/phpstan-deprecation-rules/rules.neon

Adapting to your project

Specifying your Drupal project's root

By default, the PHPStan Drupal extension will try to determine your Drupal project's root directory based on the working directory that PHPStan is checking. If this is not working properly, you can explicitly define the Drupal project's root directory using the drupal.drupal_root parameter.

parameters:
    drupal:
        drupal_root: /path/to/drupal

You can also use container parameters. For instance you can always set it to the current working directory.

parameters:
    drupal:
        drupal_root: %currentWorkingDirectory%

Entity storage mappings.

The EntityTypeManagerGetStorageDynamicReturnTypeExtension service helps map dynamic return types. This inspects the passed entity type ID and tries to return a known storage class, besides the default EntityStorageInterface. The default mapping can be found in extension.neon. For example:

parameters:
    drupal:
        entityTypeStorageMapping:
            node: Drupal\node\NodeStorage
            taxonomy_term: Drupal\taxonomy\TermStorage
            user: Drupal\user\UserStorage

To add support for custom entities, you may add the same definition in your project's phpstan.neon. See the following example for adding a mapping for Search API:

parameters:
    drupal:
        entityTypeStorageMapping:
            search_api_index: Drupal\search_api\Entity\SearchApiConfigEntityStorage
            search_api_server: Drupal\search_api\Entity\SearchApiConfigEntityStorage
