Hi Bruce

If I understand correctly.

$_SERVER['fname'] !?? $user->setName($_SERVER['fname']);


Will return the result of  $user->setName($_SERVER['fname']) if
$_SERVER['fname']  is set or null if not set. While:

isset($_SERVER['fname']) && $user->setName($_SERVER['fname']);


Will return boolean.

Cheers
