If you need support for other Google APIs, please check out the Google APIs Client Library for PHP.

Quick Start

We recommend installing individual component packages when possible. A list of available packages can be found on Packagist.

For example:

$ composer require google/cloud-bigquery
$ composer require google/cloud-datastore

We also provide the google/cloud package, which includes all Google Cloud clients.

$ composer require google/cloud


Authentication is handled by the client library automatically. You just need to provide the authentication details when creating a client. Generally, authentication is accomplished using a Service Account. For more information on obtaining Service Account credentials, see our Authentication Guide.

Once you've obtained your credentials file, it may be used to create an authenticated client.

require 'vendor/autoload.php';

use Google\Cloud\Core\ServiceBuilder;

// Authenticate using a keyfile path
$cloud = new ServiceBuilder([
    'keyFilePath' => 'path/to/keyfile.json'

// Authenticate using keyfile data
$cloud = new ServiceBuilder([
    'keyFile' => json_decode(file_get_contents('/path/to/keyfile.json'), true)

If you do not wish to embed your authentication information in your application code, you may also make use of Application Default Credentials.

require 'vendor/autoload.php';

use Google\Cloud\Core\ServiceBuilder;


$cloud = new ServiceBuilder();

The GOOGLE_APPLICATION_CREDENTIALS environment variable may be set in your server configuration.

gRPC and Protobuf

Many clients in Google Cloud PHP offer support for gRPC, either as an option or a requirement. gRPC is a high-performance RPC framework created by Google. To use gRPC in PHP, you must install the gRPC PHP extension on your server. While not required, it is also recommended that you install the protobuf extension whenever using gRPC in production.

$ pecl install grpc
$ pecl install protobuf

Caching Access Tokens

By default the library will use a simple in-memory caching implementation, however it is possible to override this behavior by passing a PSR-6 caching implementation in to the desired client.

The following example takes advantage of Symfony's Cache Component.

require 'vendor/autoload.php';

use Google\Cloud\Storage\StorageClient;
use Symfony\Component\Cache\Adapter\ArrayAdapter;

// Please take the proper precautions when storing your access tokens in a cache no matter the implementation.
$cache = new ArrayAdapter();

$storage = new StorageClient([
    'authCache' => $cache

This library provides a PSR-6 implementation with the SystemV shared memory at Google\Auth\Cache\SysVCacheItemPool. This implementation is only available on *nix machines, but it's the one of the fastest implementations and you can share the cache among multiple processes. The following example shows how to use it.

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

use Google\Cloud\Spanner\SpannerClient;
use Google\Auth\Cache\SysVCacheItemPool;

$cache = new SysVCacheItemPool();

$spanner = new SpannerClient([
    'authCache' => $cache


This library follows Semantic Versioning.

Please note it is currently under active development. Any release versioned 0.x.y is subject to backwards incompatible changes at any time.

GA: Libraries defined at a GA quality level are stable, and will not introduce backwards-incompatible changes in any minor or patch releases. We will address issues and requests with the highest priority. Please note, for any components which include generated clients the GA guarantee will only apply to clients which interact with stable services. For example, in a component which hosts V1 and V1beta1 generated clients, the GA guarantee will only apply to the V1 client as the service it interacts with is considered stable.

Beta: Libraries defined at a Beta quality level are expected to be mostly stable and we're working towards their release candidate. We will address issues and requests with a higher priority.

Alpha: Libraries defined at an Alpha quality level are still a work-in-progress and are more likely to get backwards-incompatible updates.


Contributions to this library are always welcome and highly encouraged.
