$error = array('error' => $this->upload->display_errors());

推荐答案
您可以使用CI本机选项加密文件名:
You can encrypt file name with use of CI native option:
$config['encrypt_name'] = TRUE;
OR
您可以使用自己的代码进行操作:
You can do it with your own code:
$new_name = time().$_FILES["userfiles"]['name'];
$config['file_name'] = $new_name;
