You can turn it on (don't forget to bounce the webserver) but it is intentionally off by default for security reasons. These are shown in php.ini and in the PHP manual. Global variables are something of a security risk, so it is recommended to keep them off. You can still get at all these things, but in a slightly different way. Get parameters are accesses as $_GET['name'}, post variables as $_POST['name'], php_self as $_SERVER['PHP_SELF'], $http_user_agent as $_SERVER['HTTP_USER_AGENT']. Regards Chris
