Backblaze B2 SDK for PHP

b2-sdk-php is a client library for working with Backblaze's B2 storage service. It aims to make using the service as easy as possible by exposing a clear API and taking influence from other SDKs that you may be familiar with.

Authorization requests will be cached for 1 hour to avoid hitting the B2 API limit.

History & Changes

This is a fork of the RunCloudIO version, based on the original by Chris White, with the following changes:

Installation

To install via Composer:

composer require dmhendricks/b2-sdk-php

Usage Examples

use ChrisWhite\B2\Client;
use ChrisWhite\B2\Bucket;

$client = new Client('accountId', 'applicationKey');

// Returns the base B2 file URL
$client->getDownloadUrl();

// Returns the provided bucket/file prefixed with the B2 base URL
$client->getDownloadUrl([
    'BucketName' => 'my-special-bucket',
    'FileName' => 'path/to/file'
]);

// Returns a Bucket object.
$bucket = $client->createBucket([
    'BucketName' => 'my-special-bucket',
    'BucketType' => Bucket::TYPE_PRIVATE // or TYPE_PUBLIC
]);

// Change the bucket to private. Also returns a Bucket object.
$updatedBucket = $client->updateBucket([
    'BucketId' => $bucket->getId(),
    'BucketType' => Bucket::TYPE_PUBLIC
]);

// Retrieve an array of Bucket objects on your account.
$buckets = $client->listBuckets();

// Delete a bucket.
$client->deleteBucket([
    'BucketId' => '4c2b957661da9c825f465e1b'
]);

// Upload a file to a bucket. Returns a File object.
$file = $client->upload([
    'BucketName' => 'my-special-bucket',
    'FileName' => 'path/to/upload/to',
    'Body' => 'I am the file content'

    // The file content can also be provided via a resource.
    // 'Body' => fopen('/path/to/input', 'r')
]);

// Download a file from a bucket. Returns the file content.
$fileContent = $client->download([
    'FileId' => $file->getId()

    // Can also identify the file via bucket and path:
    // 'BucketName' => 'my-special-bucket',
    // 'FileName' => 'path/to/file'

    // Can also save directly to a location on disk. This will cause download() to not return file content.
    // 'SaveAs' => '/path/to/save/location'
]);

// Delete a file from a bucket. Returns true or false.
$fileDelete = $client->deleteFile([
    'FileId' => $file->getId()

    // Can also identify the file via bucket and path:
    // 'BucketName' => 'my-special-bucket',
    // 'FileName' => 'path/to/file'
]);

// Retrieve an array of file objects from a bucket.
$fileList = $client->listFiles([
    'BucketId' => '4d2dbbe08e1e983c5e6f0d12'
]);

/*
 * Retrieve file versions from a bucket. Returns array. Optional parameters:
 *    StartFileName - The first file name to return.
 *    StartFileId - The first file ID to return. startFileName must also be
 *        provided if startFileId is specified.
 *    MaxFileCount - The maximum number of files to return.
 *    Prefix - Files returned will be limited to those with the given prefix.
 *        Defaults to the empty string, which matches all files.
 *    Delimiter - The delimiter character will be used to "break" file names
 *        into folders.
 * @see https://www.backblaze.com/b2/docs/b2_list_file_versions.html
 */
$fileVersions = $client->listFileVersions([
    'BucketId' => '4d2dbbe08e1e983c5e6f0d12',
]);
