[Schriftliche Testfrage] Schreiben Sie einen Mikrowellenherd in PHP

Ich habe im Internet eine schriftliche Testfrage gesehen, die ich sehr interessant fand, also habe ich versucht, sie zu lösen. Korrekturen sind willkommen.

Codierungsfragen (Codieren mit OOP-Ideen, auf Codespezifikationen achten) Schreiben Sie Ihre Ideen auf, am besten haben Sie Code

Schreiben Sie einen Mikrowellenherd in PHP. Beachten Sie, dass die Tür beim Erhitzen von Gegenständen nicht geöffnet werden kann und Lebensmittel mit Gürtelschalen nicht erhitzt werden können.

Vielen Dank für Ihre Vorschläge. Ich verstehe OOP jetzt besser und aktualisiere die zweite Version.
