per Tariq Adel Al Ammadi,
$USER->firstname and $USER->lastname; also, you can use fullname($USER, true), see below for the definition.
* @uses $CFG
* @uses $SESSION
* @param object $user A {@link $USER} object to get full name of
* @param bool $override If true then the name will be first name
* followed by last name rather than adhering to fullnamedisplay setting.
*/
function fullname($user, $override=false) {
...
Put var_dump($USER) in your code to see exactly what is going on inside $USER.
