It can be a web server problem. I do not know which SW you use.
Remember that e.g. Apache does not expose your environment to the
CGI/PHP scripts unless they are set in the *.conf files by PassEnv
and/or SetEnv directives. For security reasons, /tmp and /var/tmp are
not used directly, a virtual filesystem is built there and files
created by one CGI/PHP process do not exist for another CGI/PHP
process. Thus you PHP script can see the file as /tmp/something but
the real file will be /tmp/somedir/something where somedir is
unpredictable. I have my own wrappers if I need to do such things.
