php mkdir() chmod 和权限

php mkdir() chmod and permissions

提问by Thomas

i was using this basic script:

我正在使用这个基本脚本：

$folderPath = "../path/to/$folder/";
mkdir("$folderPath");

i create this directory and then upload photos to it. I've been doing this for a good 4-5 months now and suddenly i start getting 'FORBIDDEN' errors when I attempt to view the contents of the folder via web browser

我创建这个目录，然后上传照片到它。我已经这样做了 4-5 个月了，当我尝试通过网络浏览器查看文件夹的内容时，突然间我开始收到“禁止”错误

The directory is being created the same and the photos are still uploading without a problem, but I cannot access the photos

目录创建相同，照片仍在上传没有问题，但我无法访问照片

I tried rewriting the script and using chmod to change the permissions but I'm having no luck at all

我尝试重写脚本并使用 chmod 来更改权限，但我一点运气都没有

All the older folders were being created with: -w- rwx r-x r-x

使用以下命令创建所有较旧的文件夹：-w- rwx rx rx

and I can't get this recreated

我无法重新创建它

I've tried adding a chmod line into my script:

我试过在我的脚本中添加一个 chmod 行：

$folderPath = "../sales/inventory/$folder/";
mkdir("$folderPath");
chmod("$folderPath", 0755);

but I can't recreate the same permissions, I'm trying to understand how chmod works, but I can't figure out how to get this very basic function working properly again

但我无法重新创建相同的权限，我试图了解 chmod 的工作原理，但我无法弄清楚如何让这个非常基本的功能再次正常工作

Try looking out for a HTAccess file, where the "Options -Indexes" option will be mentioned, as this is mostly used for not showing the contents of a folder in a web browser. The file needs to be searched in the following manner:-

尝试查找 HTAccess 文件，其中将提到“Options -Indexes”选项，因为这主要用于不在 Web 浏览器中显示文件夹的内容。该文件需要按以下方式搜索：-

• In the folder "root_folder/sales/inventory/$folder/", where "$folder" is as mentioned in your code.
• If not found, try in the folder "root_folder/sales/inventory/".
• If not found, try in the folder "root_folder/sales/".
• If not found, try in the folder "root_folder/".

• 在文件夹“ root_folder/sales/inventory/$folder/”中，其中“ $folder”在您的代码中提到。
• 如果未找到，请在文件夹“root_folder/sales/inventory/”中尝试。
• 如果未找到，请在文件夹“root_folder/sales/”中尝试。
• 如果未找到，请在文件夹“root_folder/”中尝试。

When you get the code of "Options -Indexes" written in the HTAccess file, you can remove / comment that line of code from there, or you can also write another HTAccess file in your required folder of "$folder", where the code will be "Options Indexes".

当你得到写在 HTAccess 文件中的“Options -Indexes”的代码时，你可以从那里删除/注释那行代码，或者你也可以在你需要的“ $folder”文件夹中编写另一个 HTAccess 文件，代码将在那里“选项索引”。

Also in the PHP page, the logic must be like this:-

同样在PHP页面中，逻辑必须是这样的：-

<?php
$folderPath = "../sales/inventory/$folder/";
mkdir("$folderPath");
chmod("$folderPath", 0755);

// Use of "copy()" / "move_uploaded_file()" function here, using some "$targetFile" variable.
chmod($targetFile, 0755);
?>

This will help you when you will be unlinking / deleting the uploaded files from the "$folder" folder.

当您从“$folder”文件夹中取消链接/删除上传的文件时，这将对您有所帮助。

Hope it helps.

希望能帮助到你。

If your $folder variable includes some sub-directories your parent directories are maybe not being chmoded to the right permissions. This was the problem I was having on a hired OVH Gentoo server.

如果您的 $folder 变量包含一些子目录，您的父目录可能没有被修改为正确的权限。这是我在租用的 OVH Gentoo 服务器上遇到的问题。

Imagine that $folder = '/store1/ally23/shelf42';so your final directory structure is ../sales/inventory/store1/ally23/shelf42, and you want 0777permisions. You do:

想象一下，$folder = '/store1/ally23/shelf42';您的最终目录结构是 ../sales/inventory/store1/ally23/shelf42，并且您需要0777权限。你做：

mkdir($folderPath, 0777, true) || chmod($folderPath, 0777);

Only the final directory shelf42is chmoded to 0777. The intermediary directories are created with default permissions (in my case 0744).

只有最终目录shelf42被 chmoded 为0777. 中间目录是使用默认权限创建的（在我的情况下0744）。

There is no recursive option in PHP's chmod command, so you have to loop over the intermediary directories and chmod them individually.

PHP 的 chmod 命令中没有递归选项，因此您必须遍历中间目录并单独对它们进行 chmod。

If you're in a shared environment, you may also want to chownafter upload, to be on the safe side. Especially if you're running your web server under a user other than your virtual host has permission to access (EG: "nobody" vs "mysite".) This is common with cPanel servers, FWIW.

如果您在共享环境中，为了安全起见，您可能还想在上传后chown。特别是如果您在虚拟主机以外的用户下运行您的 Web 服务器有权访问（例如：“nobody”与“mysite”。）这在 cPanel 服务器中很常见，FWIW。
