phpunit/php-timer
Utility class for timing things, factored out of PHPUnit into a stand-alone component.
Installation
You can add this library as a local, per-project dependency to your project using Composer:
composer require phpunit/php-timer
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 phpunit/php-timer
