There are three arrays in PHP: $HTTP_GET_VARS, $HTTP_POST_VARS and
$HTTP_COOKIE_VARS that probably are what you want. In order to have
them set, you must be running PHP with the "track_vars" php3.ini option
on, or with <?php_track_vars?> in the beginning of your script.

For a GET request you'll get a list like this:

reset($HTTP_GET_VARS);
while (list($name, $value) = each($HTTP_GET_VARS)) {
    print "$name = $value<br>\n";
}

In the future, please use php3 <email protected> for questions like this.
