Object Storage Service:Create buckets by using OSS SDK for PHP

Usage notes

• In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS from other Alibaba Cloud services in the same region as OSS, use an internal endpoint. For more information about OSS regions and endpoints, see Regions and endpoints.

• In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or Security Token Service (STS), see Create an OSSClient instance.

• From 10:00 (UTC+8) on October 13, 2025, OSS will implement a phased adjustment across all regions to enable Block Public Access by default for new buckets created using the API, OSS SDKs, or ossutil. For details about the exact times when the adjustment will take effect in each region, see [Official Announcement] Adjustment to Public Access Blocking Configurations for Newly Created Buckets. Once Block Public Access is enabled, you cannot configure public access permissions, including public ACLs (public read and public read/write) and bucket policies that allows public access. You can disable this feature after the bucket is created if your business requires public access.

Permissions

By default, an Alibaba Cloud account has full permissions on resources in the account. In contrast, RAM users and RAM roles associated with an Alibaba Cloud account initially have no permissions. To manage resources by using a RAM user or role, you must grant the required permissions via RAM policies or Bucket policies.

Examples

The following sample code provides an example on how to create a bucket named examplebucket.

<?php
if (is_file(__DIR__ . '/../autoload.php')) {
    require_once __DIR__ . '/../autoload.php';
}
if (is_file(__DIR__ . '/../vendor/autoload.php')) {
    require_once __DIR__ . '/../vendor/autoload.php';
}

use OSS\Credentials\EnvironmentVariableCredentialsProvider;
use OSS\OssClient;
use OSS\CoreOssException;

// Obtain access credentials from environment variables. Before you run the sample code, make sure that the OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET environment variables are configured.  
$provider = new EnvironmentVariableCredentialsProvider();
// In this example, the endpoint of the China (Hangzhou) region is used. Specify your actual endpoint. 
$endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
// Specify the name of the bucket. Example: examplebucket. 
$bucket= "examplebucket";
try {
    $config = array(
        "provider" => $provider,
        "endpoint" => $endpoint,
        "signatureVersion" => OssClient::OSS_SIGNATURE_VERSION_V4,
        "region"=> "cn-hangzhou"
    );
    $ossClient = new OssClient($config);
    // Set the storage class of the bucket to Infrequent Access (IA). The default storage class is Standard. 
    $options = array(
        OssClient::OSS_STORAGE => OssClient::OSS_STORAGE_IA
    );
    // Set the ACL of the bucket to public-read. The default bucket ACL is private. 
    $ossClient->createBucket($bucket, OssClient::OSS_ACL_TYPE_PUBLIC_READ, $options);
} catch (OssException $e) {
    printf(__FUNCTION__ . ": FAILED\n");
    printf($e->getMessage() . "\n");
    return;
}
print(__FUNCTION__ . ": OK" . "\n");
