PHP些个代码把数据库存储的点播视频和阿里云OSS文件批量下载到本机

最近有个业务需求，需要备份数据库的视频文件，写了这个代码，用5T的硬盘拷贝数据库的点播视频文件，保持原先OSS存储的目录结构，跑个本机程序备份到本机（用TP写的PHP代码配置的路径为： http://localhost:8181/api/crontab.video/downloadVod），本机自动执行刷新，跑了2天终于把2T多的文件下载完毕了 ，以下核心代码仅供参考。

 /** 保存点播视频本地
  *  /api/crontab.video/downloadVod
  */

 function downloadVod(){
     set_time_limit(0);
     echo date('Y-m-d H:i:s').'<br>'; 
     $where = ['cate_id'=>'0','is_audit'=>['in',[0,1]],'ctime'=>['lt',gmtime()-60]];
     $video = Model('video')->where($where)->field('video_id,photo,video_url,vod_url')->order('video_id asc')->limit(2)->select(); 
     $path = "./Uploads/video";
     $path = "H:/YTS";
     if(!is_dir($path)){
         @mkdir($path, 0777,true); echo 'ok';
     }
     $new_file = '';
     foreach($video as $key=>$val){
         $photo = explode('|',$val['photo']); 
         $vod_url = $val['vod_url'];
$video_url = $val['video_url'];
if ( $vod_url != '') {
   $vod_url = str_replace('https', 'http', $vod_url);
   $url = $this->fopen_url($vod_url);
   $videoPath = parse_url($video_url)['path'];
   $new_file = $path . dirname($videoPath) . "/";
   if (!file_exists($new_file)) {
      //检查是否有该文件夹，如果没有就创建，并给予最高权限
      @mkdir($new_file, 0777, true);
   }
   $new_file = $new_file . basename($video_url);  //getFileExt($vod_url)
   file_put_contents($new_file, $url);
}

         $ret = Model('video')->where(array('video_id'=>$val['video_id']))->update(['cate_id'=>1]);
         if($ret === false){
             return '下载保存失败.';
         }
     }
     echo '<br><br>downloadCoverDone:'.$new_file.' | '.M()->getLastSql();

     echo '<meta http-equiv="refresh" content="2;url="http://localhost:8181/api/crontab.video/downloadVod"';
