PHP_Timer

Utility class for timing things, factored out of PHPUnit into a stand-alone component.

Installation

To add this package as a local, per-project dependency to your project, simply add a dependency on phpunit/php-timer to your project's composer.json file. Here is a minimal example of a composer.json file that just defines a dependency on PHP_Timer:

{
    "require": {
        "phpunit/php-timer": "~1.0"
    }
}

Usage

PHP_Timer::start();

$timer->start();

// ...

$time = PHP_Timer::stop();
