```bash
$ composer install kreait/gcp-metadata
```

```php
use Kreait\GcpMetadata;

$metadata = new GcpMetadata();
```

#### Check if the metadata server is available

```php
$isAvailable = $metadata->isAvailable();
```

#### Get all available instance properties

```php
$data = $metadata->instance();
```

#### Get all available project properties

```php
$data = $metadata->project();
```

#### Access a specific property

```php
$data = $metadata->instance('hostname');
```

#### Wrap queries in a try/catch block if you don't check for availability

```php
use Kreait\GcpMetadata;

$metadata = new GcpMetadata();

if ($metadata->isAvailable()) {
    echo $metadata->instance('hostname');
}

try {
    echo $metadata->instance('hostname');   
} catch (GcpMetadata\Error $e) {
    echo $e->getMessage();
}
```
