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
require __DIR__ . '/vendor/autoload.php';

use SebastianBergmann\Timer\Timer;

$timer = new Timer;

$timer-&gt;start();

foreach (\range(0, 100000) as $i) {
    // ...
}

$duration = $timer-&gt;stop();

var_dump(get_class($duration));
var_dump($duration-&gt;asString());
var_dump($duration-&gt;asSeconds());
var_dump($duration-&gt;asMilliseconds());
var_dump($duration-&gt;asMicroseconds());
var_dump($duration-&gt;asNanoseconds());
```

The code above yields the output below:

```
string(32) &quot;SebastianBergmann\Timer\Duration&quot;
string(9) &quot;00:00.002&quot;
float(0.002851062)
float(2.851062)
float(2851.062)
int(2851062)
```

### Resource Consumption

#### Explicit duration

```php
require __DIR__ . '/vendor/autoload.php';

use SebastianBergmann\Timer\ResourceUsageFormatter;
use SebastianBergmann\Timer\Timer;

$timer = new Timer;
$timer-&gt;start();

foreach (\range(0, 100000) as $i) {
    // ...
}

print (new ResourceUsageFormatter)-&gt;resourceUsage($timer-&gt;stop());
```

The code above yields the output below:

```
Time: 00:00.002, Memory: 6.00 MB
```

#### Duration since PHP Startup (using unreliable `$_SERVER['REQUEST_TIME_FLOAT']`)

```php
require __DIR__ . '/vendor/autoload.php';

use SebastianBergmann\Timer\ResourceUsageFormatter;

foreach (\range(0, 100000) as $i) {
    // ...
}

print (new ResourceUsageFormatter)-&gt;resourceUsageSinceStartOfRequest();
```

The code above yields the output below:

```
Time: 00:00.002, Memory: 6.00 MB
```
