# 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
