Well you could try printing out the enviromental varible "TERM".

Or you can run a shell command "uname -a".

<?php echo system("uname -a"); ?>

Just remember that the web server runs as its own user, so you'll need to make sure whatever applications you want to run have appropriate permissions. (A potential security risk)

I build a headless server at one point which allowed a web page to shut down and reboot the server, I gave user www-data sudo permissions with no password on one command, /usr/sbin/shutdown.

see man sudoers for details.

Try php_uname().
