A bucket is a container for objects stored in OSS. Every object is contained in a bucket. This topic describes how to list buckets.

For more information about how to list buckets, see GetBucket (ListObjects).

The following code provides an example on how to list all buckets:

<? 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\OssClient;
use OSS\Core\OssException;

// Security risks may arise if you use the AccessKey pair of an Alibaba Cloud account to log on to OSS, because the account has permissions on all API operations. We recommend that you use a RAM user to call API operations or perform routine operations and maintenance. To create a RAM user, log on to https://ram.console.aliyun.com.
$accessKeyId = "<yourAccessKeyId>";
$accessKeySecret = "<yourAccessKeySecret>";
// This example uses the endpoint of the China (Hangzhou) region. Specify the actual endpoint based on your requirements.
$endpoint = "http://oss-cn-hangzhou.aliyuncs.com";
    $ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);

    $bucketListInfo = $ossClient->listBuckets();
} catch(OssException $e) {
    printf(__FUNCTION__ . ": FAILED\n");
    printf($e->getMessage() . "\n");
$bucketList = $bucketListInfo->getBucketList();
foreach($bucketList as $bucket) {
    print($bucket->getLocation() . "\t" . $bucket->getName() . "\t" . $bucket->getCreatedate() . "\n");
