### 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/main/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');
```
