Say a php file has include_once("$CONF/blah.inc") in it. Where is this $CONF and the default location?

$CONF is a configuration variable set in an already sourced file. The search path is relative to at least one element from the include_path variable.
See http://www.php.net/manual/en/ini.core.php#ini.include-path for more details.
