使用 codeigniter 删除目录 [英] Removing directory using codeigniter

问题描述

我是 codeigniter 的新手，所以请原谅我，我试图让 codeigniter 删除一个基本文件夹(我不知道正确的术语是什么，这是我放置上传文件的文件夹，它位于我的 codeigniter 项目的根).由于我是 codeigniter 的新手，我不知道如何使用 codeigniter api 中的 File Helper 参考.我希望有人能帮我解决这个问题.

I'm new to codeigniter so please forgive me, I am trying to make codeigniter delete a base folder (I don't know what the right term is, it's the folder where I put my uploaded files and its located in the root of my codeigniter project). Since I am new to codeigniter, I don't have any idea on how to make use of the File Helper reference in the codeigniter api. I hope someone can help me with this.

此外，我尝试创建的删除功能还需要删除其所有内容，无论是否为空，文件夹都会被删除.我猜，它会使用递归类型的删除...我一点也不确定.

Furthermore, the delete function I am trying to make needs to delete also all of its contents, so empty or not, the folder gets deleted. I'm guessing, it would use a recursive type of deletion...I'm not so sure at all.

推荐答案

您可以使用 delete_files 函数

$path=$this->config->base_url().'dir_name';
$this->load->helper("file"); // load the helper
delete_files($path, true); // delete all files/folders

以上代码将删除给定路径中的所有文件和文件夹，如果目录为空，则您可以使用 rmdir 删除空目录，如

Above code will delete all files and folders from the given path and if once the directory is empty then you can use rmdir which deletes an empty directory, like

rmdir($path);

文件夹应该允许相关权限，这意味着文件/文件夹必须是可写的或由系统拥有才能被删除.

The folder should permit relevant permissions, which means files/folder must be writable or owned by the system in order to be deleted.
