To begin, install the preferred dependency manager for PHP, Composer.

Now install this component:

$ composer require google/cloud-storage


Please see our Authentication guide for more information on authenticating your client. Once authenticated, you'll be ready to start making requests.


require 'vendor/autoload.php';

use Google\Cloud\Storage\StorageClient;

$storage = new StorageClient();

$bucket = $storage->bucket('my_bucket');

// Upload a file to the bucket.
    fopen('/data/file.txt', 'r')

// Using Predefined ACLs to manage object permissions, you may
// upload a file and give read access to anyone with the URL.
    fopen('/data/file.txt', 'r'),
        'predefinedAcl' => 'publicRead'

// Download and store an object from the bucket locally.
$object = $bucket->object('file_backup.txt');

Stream Wrapper

require 'vendor/autoload.php';

use Google\Cloud\Storage\StorageClient;

$storage = new StorageClient();

$contents = file_get_contents('gs://my_bucket/file_backup.txt');


This component is considered GA (generally available). As such, it will not introduce backwards-incompatible changes in any minor or patch releases. We will address issues and requests with the highest priority.
