Requirements

These are the constraints enforced by Composer when you install cboxdk/system-metrics. They come directly from the package's composer.json.

PHP Version

• PHP ^8.3 — PHP 8.3 or any later 8.x release.

The 8.3 floor is a hard requirement: the library relies on readonly classes and the modern type system introduced in PHP 8.3.

Dependencies

This package is intentionally dependency-light:

• No runtime Composer dependencies. The require section declares only the PHP version constraint — installing the package pulls in no third-party runtime packages.
• No required PHP extensions. composer.json declares no ext-* requirements, so nothing beyond a standard PHP build is needed to satisfy the resolver.

Development-only tooling (Laravel Pint, Pest, PHPStan) is declared under require-dev and is not installed for consumers of the library.
