Abstraction for most of the operating system the PHP code run on.

The goal is to deal with the operating system in a more abstract way (instead of dealing with concrete, low level, details).

Important

you must use vimeo/psalm to make sure you use this library correctly.

Installation

composer require innmind/operating-system
