# 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
### Basic Timing
```php
PHP_Timer::start();
$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
