ease of application development. While the Cloud Firestore interface has many of
the same features as traditional databases, as a NoSQL database it differs from
them in the way it describes relationships between data objects.

### Installation

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

Now install this component:

This component requires the gRPC extension. Please see our [gRPC installation guide](https://cloud.google.com/php/grpc)
for more information on how to configure the extension.

$firestore = new FirestoreClient();

$collectionReference = $firestore->collection('Users');
$documentReference = $collectionReference->document($userId);
$snapshot = $documentReference->snapshot();

echo "Hello " . $snapshot['firstName'];
```
