What is the difference between public private and protected

Question

When and why should I use public, private, and protected functions and variables inside a class? What is the difference between them?

Answer 1

• public scope to make that property/method available from anywhere, other classes, and instances of the object.

• private scope when you want your property/method to be visible in its own class only.

• protected scope when you want to make your property/method visible in all classes that extend the current class including the parent class.

I hope this helps you.
