# 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](https://getcomposer.org/):
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
## Usage
### Basic Timing
```php
PHP_Timer::start();
// ...
$time = PHP_Timer::stop();
var_dump($time);
print PHP_Timer::secondsToTimeString($time);
```
The code above yields the output below:
double(1.0967254638672E-5)
0 ms
### Resource Consumption Since PHP Startup
```php
print PHP_Timer::resourceUsage();
```
The code above yields the output below:
Time: 0 ms, Memory: 0.50MB
