Chmod of the partition /home/myapplication

[Frederic Guillet <fguillet@gmail.com>]

Hi,

I am developing a web service in php that will allow people to back up
some documents into a private virtual disk.

the pb is that i have to chmod so that people can write onto their
disk. here is my existing configuration:

/home = 40755
/home/myapplication = 42755
/home/myapplication/disk (where each user has a folder to store data) = 47777

Is there any parameters to change somewhere in order to solve the pb
and remove 777?

Many thanks in advance for yor clever help.

Best Regards,
