Is it ever necessary to define a method as "public"?

Question

If all methods are publicly available, if they are not explicitly defined as something else, should the method ever be defined as public?

Answer 1

Well, you already answered the question by specifying by default: no, this is not necessary.

To quote the manual :

Class methods can be defined as public, private, or protected. Methods declared without any explicit visibility keyword are defined as public.

However, I think this is always good.

Answer 2

public , .

Answer 3

There are two style trends in php: "javaesque" the majority considers visibility modifiers to be very important and actively use them, in the Pitonesian minority (I personally belong) we consider that everything that is a public-private interface is nothing more than memory loss.
