Chris@0: # PHP_Timer
Chris@0: 
Chris@0: Utility class for timing things, factored out of PHPUnit into a stand-alone component.
Chris@0: 
Chris@0: ## Installation
Chris@0: 
Chris@0: You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
Chris@0: 
Chris@0:     composer require phpunit/php-timer
Chris@0: 
Chris@0: 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:
Chris@0: 
Chris@0:     composer require --dev phpunit/php-timer
Chris@0: 
Chris@0: ## Usage
Chris@0: 
Chris@0: ### Basic Timing
Chris@0: 
Chris@0: ```php
Chris@0: PHP_Timer::start();
Chris@0: 
Chris@0: // ...
Chris@0: 
Chris@0: $time = PHP_Timer::stop();
Chris@0: var_dump($time);
Chris@0: 
Chris@0: print PHP_Timer::secondsToTimeString($time);
Chris@0: ```
Chris@0: 
Chris@0: The code above yields the output below:
Chris@0: 
Chris@0:     double(1.0967254638672E-5)
Chris@0:     0 ms
Chris@0: 
Chris@0: ### Resource Consumption Since PHP Startup
Chris@0: 
Chris@0: ```php
Chris@0: print PHP_Timer::resourceUsage();
Chris@0: ```
