PHP mkdir 0777 fail chmod 0777 works

There is something like this in my PHP code:

$ success = mkdir ($ directory_name, 0777, TRUE);

When I look at the actual folder that he created, the permissions are 0755. Any ideas what could be causing this?

Answer 1

Actual permissions are affected by the current umask() value. If it is limited to 755 , then directory permissions. (He xor canceled the requested 777 )

Answer 2

Your umask is probably set to 0022 (common by default), not allowing write bits to be set for the group and others. You can use the umask function to change the current umask.

But why, why do you create a directory that can be written in the world? Not a good idea.
