PHP：为什么chmod（）将我的文件/文件夹设置为555或444？

Question

I created a web application with a file browser. I'm trying to add a functionality where the user can change the chmod/permissions via an ajax request which is handled via PHP on the back-end.

(Side Note: I'm running my local with WAMP)

So initially, I'm reading the permissions with this

substr(sprintf('%o', fileperms($relativePath)), -4)

to get this format (0777, 0644, etc), if not it returns something like 32726. This info is used to be displayed in the UI for the user to know whats current.

However, when I run the script, I set it to 0777 and it seems to run fine. But then when I read the file again, it returns 0555 or 0444. Anyone know what I'm missing?

Answer 1

I realized this was not an issue, but rather the chmod command does not work properly on a windows/apache setup.
