HTTP variables

Hello,
I've got an issue with php4 that i suspect has to do with
register_globals being off. I want to access the HTTP_* variables exported
by apache. I would normally do this via:
echo "$HTTP_USER_AGENT";
with register_globals off this isn't working. This request isn't part of a
form so the $_GET and $_POST arrays won't have it. According to phpinfo()
the variable is being set i am unable to find it. Any help appreciated.
Thanks.
Dave.

Must be my turn for the obligatory daily RTFM request...

RTFM:

http://www.php.net/reserved.variables

Use...

print $_SERVER['HTTP_USER_AGENT'];

or for older PHPs...

global $HTTP_SERVER_VARS;
print $HTTP_SERVER_VARS['HTTP_USER_AGENT'];

Sure, but the $_SERVER will... Try $_SERVER['HTTP_USER_AGENT'].
