Uploading through php blocked?

I'm working on a server now which sets all my uploaded files (uploaded through php) at 600 permissions. chmod doesn't work, umask doesn't either. I also can't change permissions through ftp. I can make directories through php and those get 755 permissions but if I then upload a file in that directory (which should have the same owner?) it gets 600 permissions and I seem to be unable to change it. The only way uploading works is if I upload via ftp but I'm making a website which requires uploading through a form.

Can it be that my provider has blocked this somehow? The provider has a CMS system available for me which uses chmod and umask which does work but since I need to do something the CMS system can't do that's not an option.

Could chmod and umask be blocked only for specific directories? Can I check this somehow without having access to php.ini file?

My research implies your problem is due to safe mode.  Please see this page for the references:

http://www.php.net/manual/en/features.safe-mode.functions.php

When PHP creates a file, it is created by the UID/GID assigned to the web server, usually apache or httpd.  When safe mode is engaged, PHP will check to make sure the UID owning the file is the same as the UID requesting the mode change.  If it is not, chmod() will fail.

One workaround I've seen for this is to use the FTP functions within PHP.  Check out ftp_chmod():
