Refactoring to match In this refactoring we change a switch statement to a match statement https://www.php.net/manual/en/control-structures.match.php
requires: php 8.0.0

The match expression branches evaluation based on an identity check of a value. Similarly to a switch statement, a match expression has a subject expression that is compared against multiple alternatives. Unlike switch, it will evaluate to a value much like ternary expressions. Unlike switch, the comparison is an identity check (===) rather than a weak equality check (==). Match expressions are available as of PHP 8.0.0.

Original code



        $status = (int)$args['status'];

        switch ($status) {
            case 1:
                $notifier = $this->sendPendingNotification();
                break;
            case 2:
                $notifier = $this->sendAcceptedNotification();
                break;
            case 3:
                $notifier = $this->sendRejectedNotification();
                break;
            case 4:
                $notifier = $this->sendBlockedNotification();
            default:
                $notifier = $this->sendDefaultNotification();
                break;
        }

        

Refactored code



        $status = (int)$args['status'];

        $notifier = match ($status) {
            self::PENDING => $this->sendPendingNotification(),
            self::ACCEPTED => $this->sendAcceptedNotification(),
            self::REJECTED => $this->sendRejectedNotification(),
            self::BLOCKED => $this->sendBlockedNotification(),
            default => $this->sendDefaultNotification()
        };

        

Here is the output of the code
