👁 Packagist

NOTE: This repository is part of Google Cloud PHP. Any support requests, bug reports, or development contributions should be directed to that project.

Allows world-wide storage and retrieval of any amount of data at any time. You can use Cloud Storage for a range of scenarios including serving website content, storing data for archival and disaster recovery, or distributing large data objects to users via direct download.

Installation

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

Now install this component:

$ composer require google/cloud-storage

Authentication

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

Sample

require 'vendor/autoload.php';

use Google\Cloud\Storage\StorageClient;

$storage = new StorageClient();

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

// Upload a file to the bucket.
$bucket->upload(
 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.
$bucket->upload(
 fopen('/data/file.txt', 'r'),
 [
 'predefinedAcl' => 'publicRead'
 ]
);

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

Stream Wrapper

require 'vendor/autoload.php';

use Google\Cloud\Storage\StorageClient;

$storage = new StorageClient();
$storage->registerStreamWrapper();

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