The name is a private variable, measured with isset () as ture, I know that I can use unset to delete the name in the object, could I do something else with name?

As long as you have permission, you can do any action
assignment, acquisition, etc. are all possible.
The definition of private, but also to operate, it is not necessary to define the private ah? permissions, what permissions?

The current class is free to manipulate.
Your wallet is private, that's for sure, right?
So can you take money from this purse or put money in it?
Of course, you have the right to throw it away.
I get it. Is that when an object is instantiated by the class, that object can do anything to the private variable. However, objects instantiated by other classes do not have permission to operate.
Doshe!
Are you sure you understand? After the class is instantiated, the private property cannot be accessed, cannot be assigned, and cannot be inherited by the quilt class.
