This component provides functionality that helps writing PHP code that has runtime-specific (PHP / HHVM) execution paths.
You can add this library as a local, per-project dependency to your project using Composer:
composer require sebastian/environment
If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
composer require --dev sebastian/environment
