Why can't PHP create a directory with 777 permissions?

Question

I\'m trying to create a directory on my server using PHP with the command:

mkdir(\"test\", 0777);

But it doesn\'t give full permissions, on

Answer 1

The creation of files and directories is affected by the setting of umask. You can create files with a particular set of permissions by manipulating umask as follows :-

$old = umask(0);
mkdir("test", 0777);
umask($old);
