Not at all. PHP has a different and separate security model. Yes, they (the 
cgi and your PHP script) may be looking for the same environment variable, 
but they both have their own internal method of referring to it. As long as 
PHP is configured with track_vars on and register_globals off, you will need 
to query the appropriate $HTTP_SERVER_VARS["name"] (or $HTTP_POST_VARS , 
$HTTP_GET_VARS , etc) in your PHP script to get the variable into it.

eg 
<?php
if($HTTP_SERVER_VARS["REMOTE_ADDR"]) $ip = $HTTP_SERVER_VARS["REMOTE_ADDR"];
?>

will put the IP address into the $ip variable. You can refer to it as 
$HTTP_SERVER_VARS["REMOTE_ADDR"]
but that becomes a pain if you need it more than once!
