Спасибо
alexdjachenko за наводку, сделал функцию, вот исходники
$userid = $_GET['userid']; //id студента
$courseid = $_GET['courseid']; //id курса
require_once('config.php');
require_once('lib/setup.php');

$instance = $DB->get_record('enrol', array('courseid'=>$courseid, 'enrol'=>'manual'), '*', MUST_EXIST);
$course = $DB->get_record('course', array('id'=>$instance->courseid), '*', MUST_EXIST);
$today = time();
$today = make_timestamp(date('Y', $today), date('m', $today), date('d', $today), 0, 0, 0);
if(!$enrol_manual = enrol_get_plugin('manual')) { throw new coding_exception('Can not instantiate enrol_manual'); }
