If you are using Apache and the apache2handler SAPI , you can use SetEnv ; you can also export the variable from the init script that starts the PHP process (works for all SAPIs). For example, on most (older) Linux-based distros, you'll probably find a file named /etc/init.d/apache2 or /etc/init.d/httpd that is a shell script where you can export variables for that service. Check your OS' equivalent of "man 5 init" for specifics.
