Answer 2

usual php script file extension is '.php', but depending on server configuration running php interpreter, could be anything else (including specific extension to target specific php versions): you should refer to your php interpreter / server documentation to know wich is the one(s) you should use (basically, if not unusual configurtion, '.php' should work and run the default php version interpreter bundled with your server).

Answer 3

.php
