Normally you can only change this when you're the
system manager ('root'), but I'm looking now on
the system that hosts one of my sites and there
I seem to own the /tmp directory that I and my
applications see. It's a kind of virtual private
Unix server.
When you have a shell login, try this:
- cd /tmp
- chown . <your_user_name>
This probably gives an error warning.
- chmod u+rw .
This probably also gives an error warning.
There are also permission commands under FTP I think.
Otherwise contact your system manager.
There are a lot of applications like 'vi' that
don't work or don't work properly without
read and write access to the /tmp directory.
By the way, your second problem about not being
able to send the cookies can be solved by putting
ob_start(); as the first command in your PHP-file.
Make sure you really insert this as the first command.
You can't even output an empty line first for example
in the HTML part (so outside of the <?php and ?>),
also not in an include file.
You can read much more about this in the manual
under output buffering and the header() function
etc.
