This project provides a [`composer`](https://getcomposer.org) package with rules for [`phpstan/phpstan`](https://github.com/phpstan/phpstan).

## Installation

Run

```sh

composer require --dev ergebnis/phpstan-rules

```

## Usage

All of the [rules](https://github.com/ergebnis/phpstan-rules#rules) provided (and used) by this library are included in [`rules.neon`](rules.neon).

When you are using [`phpstan/extension-installer`](https://github.com/phpstan/extension-installer), `rules.neon` will be automatically included.

Otherwise you need to include `rules.neon` in your `phpstan.neon`:

```neon

includes:

	- vendor/ergebnis/phpstan-rules/rules.neon

```

:bulb: You probably want to use these rules on top of the rules provided by:

- [`phpstan/phpstan`](https://github.com/phpstan/phpstan)

- [`phpstan/phpstan-deprecation-rules`](https://github.com/phpstan/phpstan-deprecation-rules)

- [`phpstan/phpstan-strict-rules`](https://github.com/phpstan/phpstan-strict-rules)
