What is the optimal number of functions that a class should have? (best practices)?

Question

OOP

read that for the sake of 2 functions it is not necessary to create a class.
I would like to know for the sake of how much this can already be done.
The php language, well, in the trailer, it does not have any fundamental significance.

Answer 1

I read that for the sake of 2 functions you should not create a class

For the sake of functions, a class does not need to be created at all. A class needs to be created when you need to represent a certain entity. And there should be as many methods as this entity implies.

Answer 2

So much so that modularity is visible and at the same time the class is not overloaded with unnecessary code. By eye in general.
