Description:
------------
---
From manual page: https://php.net/function.umask
---
Umask function seems to accept parameter in reverse binary code.
Full access is not umask(0777), but umask(0000)
-rwxrwx--- is not umask(0770), but umask(0007)
-rwxrwxr-x is not umask(0775), but umask(0003)

Please, update documentation and add more examples.

Actual result:
--------------
When I write 
umask(0777)
I have no permissions to a directory/file

When I write 
umask(03)
I have -rwxrwxr-x permissions to a directory/file

As stated in the top comment, umask is about revoking permissions, not granting them. This is how the standard umask(2) works.
