👋 Bonjour ! Je suis Alphonsio le robot. Posez moi une question, je vais tenter d'y répondre.

Quel est le pluriel de camping-car ?

You cannot make strict type comparisons in PHP switch case. In other words, you can't use a === comparison in switch statements as stated in the documentation:

Note:Note that switch/case does loose comparison.

Loose comparison is the opposite of strict comparison.
