Copying a Versioning Object

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 example code is as follows:

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

$resp = $obsClient->copyObject([
       'Bucket' => 'destbucketname',
       'Key' => 'destobjectname',
       // Set the version ID of the object to be copied.       
       'CopySource' => 'sourcebucket/sourceobjectname?versionId=versionid'
]);

printf ("RequestId:%s\n", $resp ['RequestId']);
