The problem of renaming directories under PHP failed

Environment win7, server IIS, just discovered

Use mkdir to create a folder, but rename cannot rename the directory (file renaming can), the other rmdir seems to have no effect.
Don't know what the problem is? Permissions? Or a grammatical error?

The problem is with permissions, the folder does not modify the permissions for the user, and therefore returns false after the function executes. The workaround that I use is to directly set the permissions of the entire parent folder to the user as modifiable, and then you can. ...... But I have a little question, so does setting up security come with it? ...... Ask yourself, uh.
