mkdir and directory permissions

Hi-ya all, here's a quickie....... In my script I create a directory (mysql.backup.timestamp/) within a directory called backup/. I use the function mkdir("mysql.backup.timestamp", "0777"); and it shows the permissions as after the function executes: dr----x--t 2 nobody daemon 1024 Oct 24 15:16 mysql.backup.October-24-2002-1516 Where's the permissions (dr----x--t 2 nobody daemon) coming from? Is it the php.ini, apache conf or the operating system? I would like to set the owner to "root" and the group to "nc". How can this be achieved by the php script? Or do I have set this up in the other environments (OS or Apache)? Cheers! -Matias
