The code is as follows:

Public function getName () {
Return $this- > name

Class Bar extends Foo

Var_dump ($bar- > name)
Var_dump ($bar- > getName ())
access control
Access control to a property or method is achieved by adding the keyword public, protected, or private. A class member defined by public can be accessed anywhere; a class member defined by protected can be accessed by a subclass and parent of its class (of course, the class in which it belongs can also be accessed); and a class member defined by private can only be accessed by its own class.
