  if(@ftp_login($ftp, $ftp_user, $ftp_pass)) {
    echo "Connected as $ftp_user@$ftp_server\n";

    //尝试删除$文件
    if (ftp_delete($ftp, $file)) {
      echo "$file is deleted successfully\n";
    } else {
      echo "Could not delete $file.\n";
    }
    
  } else {
    echo "Couldn't connect as $ftp_user\n";
