Variables are accesible via :

$_SERVER["LAYOUT_HOME"] and $_SERVER["PROJECT_BASE"] global variable.

A simple test if to execute the next command in php

<?php phpinfo(); ?>

and check if the variable is present and is defined.

If not, then may be exist some restricting in the php installation ( for example in a share ambiance - sharedhosting)

So far it's not possible. All you can do is to set request headers with RequestHeader. So you'll have you variable in environ but with "HTTP_" prefix.
