var_dump.. etc returns string(15) ""

disable_functions shows as none in phpinfo!

However I've just noticed in the domain logs that its logging IP's not
hostnames, I assume this is wrong given "HostnameLookups On" is in a
conf file that is included by httpd.conf. Is there any way to confirm
at runtime that this directive is being obeyed?
