Copying an object from one Amazon S3 bucket to another using PHP

Question

I'm trying to copy a folder from one S3 bucket to another using PHP but it is causing me problems. I can create the folder I want but I cannot copy from one folder to another. Here is my code. Any help would be greatly appreciated

$key = '123';
$secret = '123';

$bucket = 'bck-users';
$keyname = $username;

try {
            //Create bucket for user
            $s3 = Aws\S3\S3Client::factory(array(
            'region' => 'eu-west-1',
            'version' => '2006-03-01',
            'credentials' => array(
              'key' => $key,
              'secret' => $secret,
                )
            ));

            $result = $s3->putObject(array(
              'Bucket' => $bucket,
              'Key'    => $keyname,
            ));

            echo $result['ObjectURL'] . "\n";

        }
        catch (Exception $e){
          echo $e->getMessage() . "\n";
        }

        //Copy default files to bucket
        $sourceBucket = 'bck-users';
        $sourceKeyname = 'default';
        $targetBucket = $username;
        $targetKeyname = 'default';             

        // Instantiate the client.
        $s3 = S3Client::factory(array(
            'region' => 'eu-west-1',
            'version' => '2006-03-01',
            'credentials' => array(
              'key' => $key,
              'secret' => $secret,);

        // Perform a batch of CopyObject operations.
        $batch = array();
        $batch[] = $s3->getCommand('CopyObject', array(
                'Bucket'     => $targetBucket,
                'Key'        => $targetKeyname,
                'CopySource' => $sourceBucket/$sourceKeyname,
            ));
        }
        try {
            $successful = $s3->execute($batch);
        } 
        catch (Exception $e){
          echo $e->getMessage() . "\n";
        }

Answer 1

$s3Client = new S3Client([
  'region' => 'ap-southeast-1',
  'version' => 'latest',
  'credentials' => [
    'key' => Yii::$app->params['key'],
    'secret' => Yii::$app->params['secret'],
  ]
]);

$result = $s3Client->copyObject([
  'Bucket' => Yii::$app->params['bucket'],
  'CopySource' => 'sourcebucketname/objectkey',
  'Key' => 'tragetbucketname/tragetkey',
]);

return $result;

Answer 2

Hi to everyone who comes here.

I suggest a copy method that can copy to another bucket.

public function CopyFile(string $key, $to)
{
    $s3Client = new S3Client([
                'version' => 'latest',
                'region' => self::AWS_REGION,
                'credentials' => [
                    'key' => self::AWS_KEY,
                    'secret' => self::AWS_SECRET
                ]
            ]);
    $s3Client->copy(self::BUCKET_NAME, $key, self::BUCKET_NAME, $to);
}
