PHPCS Differing Results POC

This repo shows PHPCS will provide different results when running against single and multiple files.

To reproduce the issue:

1. git clone this repo and cd into the project root
2. composer install to install dependencies
3. Run ./vendor/bin/phpcs
4. Run ./vendor/bin/phpcs category.php
5. Notice PHPCS flags warnings in category.php only when run against the project

Expected output of ./vendor/bin/phpcs:

W. 2 / 2 (100%)
