Copying an Object Version

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see API Reference.

You can call ObsClient->copyObject to copy an object version by specifying its versionId in the CopySource parameter.

This example specifies versionId to copy sourceobjectname of the specified version from sourcebucketname to destbucketname as destobjectname.

The sample code is as follows:

<?php

// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during the installation with the source code.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
// Create an ObsClient instance.
$obsClient = new ObsClient([ 
    // Obtain an AK/SK pair using environment variables (recommended) or import an AK/SK pair in other ways. Using hard coding may result in leakage.
    //Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
    'key' => getenv('ACCESS_KEY_ID'),
    'secret' => getenv('SECRET_ACCESS_KEY'),
    'endpoint' => 'https://your-endpoint',
]);

For details about the meanings, causes, and handling methods of error codes that may be returned during the operation, see SDK Error Codes.
