# 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
```bash
composer require --dev phpstan/phpstan
```

## Config
```yaml
# grumphp.yml
grumphp:
    tasks:
        phpstan:
            autoload_file: ~
            configuration: ~
            level: 0
            force_patterns: []
            ignore_patterns: []
            triggered_by: ['php']
            memory_limit: "-1"
```

**configuration**

*Default: null*

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

**level**

*Default: 0*
