Subject: use $HTTP_SERVER_VARS, in case register_globals is Off, and use !empty()
X-Git-Tag: php-4.0.5RC1~417
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=00b84703f8447c1d68943322038ce25030f6aa0e;p=php

use $HTTP_SERVER_VARS, in case register_globals is Off, and use !empty()
instead of just if () to avoid errors.
