### Installation

To begin, install the preferred dependency manager for PHP, [Composer](https://getcomposer.org/).

Now to install just this component:

```sh
$ composer require google/cloud-iot
```

Or to install the entire suite of components at once:

```sh
$ composer require google/cloud
```

### Authentication

on authenticating your client. Once authenticated, you'll be ready to start making requests.

### Sample

require 'vendor/autoload.php';

use Google\Cloud\Iot\V1\DeviceManagerClient;

$deviceManager = new DeviceManagerClient();

$projectId = '[MY_PROJECT_ID]';
$location = 'us-central1';
$registryId = '[MY_REGISTRY_ID]';
$registryName = $deviceManager->registryName($projectId, $location, $registryId);
$devices = $deviceManager->listDevices($registryName);
foreach ($devices->iterateAllElements() as $device) {
    printf('Device: %s : %s' . PHP_EOL,
        $device->getNumId(),
        $device->getId()
    );
}
```
