I don’t have a php version 8x installation yet to test with.

Up to now that is the way I have been programming.
I generally have one public method that reads $_GET or $_POST vars and calls
the appropriate member methods with self:methodName() and then returns whatever
the self::memberName() call returns.

The classes I define are generally tightly coupled with user interface that is largely
managed by javascript. The javascript sanitizes the input before sending sync or
async queries.

But I would expect there are lots of criticisms and questions to be sent my way.

Nope: I am not misunderstanding static methods
or
nope: $this does not make a method non static?

That is just the way I have been doing it.
with private static variables I can reference them with ‘self::varName'
