如何为我的PHP类选择正确的架构？

Question

This is the first web app that i am building by myself.

Before coding i like to organize my ideas, do class and requiriments diagrams.

So i have to do this in my software

-Add users. -Add buy orders.

I am thinking my classes in two different ways.

Like this:

class User{
    function add()
    function edit()
}

class BuyOrder{
    function add()
    function edit()
}

Or

class Add{
   function user()
   function buyOrder()
}

class Edit{
    function user()
    function buyOrder()
}

As you can see they will do the same but with different writting.

Any ideas?

thanks

Answer 1

I think User and BuyOrder should be a class.

However, it doesn't make sense to me to have an add function be a part of these classes since the creation of a new instance of these classes effectively is the add.

Instead I would create AddUser and AddOrder functions which create the instances and properly add them where they need to be.
