The Nullsafe operator, introduced in PHP 8.0, is a game-changer for handling nullable properties and method calls more gracefully. It allows you to avoid verbose null checks, making your code cleaner and more readable.
Example Tradition Null Check
$userCountry = null;
if ($user !== null) {
if ($user->getAddress() !== null) {
$userCountry = $user->getAddress()->getCountry();
}
}
