That's the way safe-mode works.

The files going into the users/ folder are created by the "apache"
(webserver) user.

The script running is owned by your account (eg "sample").

Since the UID's aren't the same you can't do anything.

See http://www.php.net/features.safe-mode

You could ask the host if they can enable safe_mode_gid and make sure
that your user and the apache user are in the same group but that's
about all you can do apart from disabling safe-mode.

(there are no workarounds, that's just the way it works).
