# Google Cloud Storage for PHP > Idiomatic PHP client for [Cloud Storage](https://cloud.google.com/storage/). [![Latest Stable Version](https://poser.pugx.org/google/cloud-storage/v/stable)](https://packagist.org/packages/google/cloud-storage) [![Packagist](https://img.shields.io/packagist/dm/google/cloud-storage.svg)](https://packagist.org/packages/google/cloud-storage) * [API documentation](http://googleapis.github.io/google-cloud-php/#/docs/cloud-storage/latest) **NOTE:** This repository is part of [Google Cloud PHP](https://github.com/googleapis/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](https://getcomposer.org/). Now to install just this component: ```sh $ composer require google/cloud-storage ``` Or to install the entire suite of components at once: ```sh $ composer require google/cloud ``` ### Authentication Please see our [Authentication guide](https://github.com/googleapis/google-cloud-php/blob/master/AUTHENTICATION.md) for more information on authenticating your client. Once authenticated, you'll be ready to start making requests. ### Sample ```php 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 ```php require 'vendor/autoload.php'; use Google\Cloud\Storage\StorageClient; $storage = new StorageClient(); $storage->registerStreamWrapper(); $contents = file_get_contents('gs://my_bucket/file_backup.txt'); ``` ### Version 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. ### Next Steps 1. Understand the [official documentation](https://cloud.google.com/storage/docs). 2. Take a look at [in-depth usage samples](https://github.com/GoogleCloudPlatform/php-docs-samples/tree/master/storage/).
