Use the AWS SDK for PHP with Backblaze B2

You can take advantage of Backblaze B2 Cloud Storage using the AWS SDK for PHP alongside the Backblaze S3-Compatible API.

Pre-Signed URLs that are generated with the PHP SDK are not currently compatible with Backblaze B2. 

When you create a Backblaze B2 bucket, select the Allow List All Bucket Names checkbox. This option is required for the List Buckets operation). If you did not select this when you created your application key, you must create a new application key with this permission enabled.

This example shows how you create a bucket using the AWS SDK for PHP with a profile named b2 in the ~/.aws/credentials file.

// Include the SDK using the Composer autoloader
require '<path for>/vendor/autoload.php';

use Aws\S3\S3Client;

// Instantiate the S3 client using your B2profile
$s3Client = S3Client::factory(array(
'endpoint' => 'https://s3.us-west-002.backblazeb2.com',
'profile' => 'b2',
'region' => 'us-west-002',
'version' => 'latest',
));

//Sample to create a bucket
$s3Client->createBucket(array('Bucket' => '<bucket-name>'));
