S3 - 需要从 AWS 下载特定映像并以 zip 格式下载

我需要将图像从 AWS 存储桶下载到本地目录并压缩下载它们。

我已经尝试了我的代码，但无法弄清楚如何将图像复制到我的本地目录中。

这是我的函数：

     public function commomUpload($contentId,$prop_id)
 {
    $client = S3Client::factory(array(
                'key' => 'my key',
                'secret' => '----secret-----',
            ));
    $documentFolderName = 'cms_photos';
    $docbucket = "propertiesphotos/$prop_id/$documentFolderName";
            $data = $this->Photo->find('all',array('conditions'=>array('Photo.content_id'=>$contentId)));
    //pr($data);die;
    $split_point = '/';
    foreach($data as $row){
        $string = $row['Photo']['aws_link'];
        $result = array_map('strrev', explode($split_point, strrev($string)));
        $imageName = $result[0];
        $result = $client->getObject(array(
            'Bucket' => $docbucket,
            'Key'    => $imageName
        ));
        $uploads_dir = '/img/uploads/';
        if (!copy($result, $uploads_dir)) {
            echo "failed to copy $result...'n";
        }
        //move_uploaded_file($imageName, "$uploads_dir/$imageName");
    }
}
