ok, here are two hints:
from the bash-help:
==============================================================
umask: umask [-S] [mode]
The user file-creation mask is set to MODE. If MODE is omitted, or if
-S' is supplied, the current value of the mask is printed. The `-S'
option makes the output symbolic; otherwise an octal number is output.
If MODE begins with a digit, it is interpreted as an octal number,
otherwise it is a symbolic mode string like that accepted by chmod(1).
==============================================================
or better description (user comments!):
http://www.php.net/manual/en/function.umask.php
the umask just applies to newly created files or directories.

as described above only the fopen, mkdir,... calls AFTER the umask are
influenced. and it depends on the server side language you are using, if
you have to reset the umask before the end of the script.
and: i am not sure if the umask works for uploads. because i.e. php
creates a tmp-file. but this happens before the php-code is reached. so
setting the umask is only working if you copy the files by hand.
but i think for a better help you should consult a mailinglist/news
group which discusses problems for the specific language.
