PHPStan

The PHPStan task focuses on finding errors in your code without actually running it. It catches whole classes of bugs even before you write tests for the code. It lives under the phpstan namespace and has following configurable parameters:

Composer

composer require --dev phpstan/phpstan

Config

# grumphp.yml
grumphp:
    tasks:
        phpstan:
            autoload_file: ~
            configuration: ~
            level: null
            force_patterns: []
            ignore_patterns: []
            triggered_by: ['php']
            memory_limit: "-1"
            use_grumphp_paths: true

autoload_file

Default: null

With this parameter you can specify the path your project's additional autoload file path.

configuration

Default: null

With this parameter you can specify the path your project's configuration file.

level

Default: null

With this parameter you can set the level of rule options - the higher, the stricter. You must either specify a level in GrumPHP or inside the phpstan.neon file.

force_patterns

Default: []

This is a list of patterns that will be forced for analysis even when the file or path is ignored.

ignore_patterns

Default: []

This is a list of patterns that will be ignored by phpstan. With this option you can skip files like tests. Leave this option blank to run phpstan for every php file.

triggered_by

Default: [php]

This is a list of extensions to be sniffed.

memory_limit

Default: null

With this parameter you can specify the memory limit.

use_grumphp_paths

Default: true

Since there is no --changed-files flag in PhpStan yet, this flags allows you to change what files will be validated. You can choose to use the paths detected by GrumPHP, or you can choose to fall back on the PhpStan configuration.
