Class Foo { Private $ name = 'hdj '; Public function getName (){ Return $ this-> name; } } Class Bar extends Foo { Public $ name = 'deleka '; } $ Bar = new Bar; Var_dump ($ bar-> name ); Var_dump ($ bar-> getName ()); Php access control description: Access control for properties or methods is implemented by adding the public, protected, or private keywords to the front. Class members defined by public can be accessed anywhere. class members defined by protected can be accessed by subclass and parent classes of their classes (of course, the class where the member is located can also be accessed), while the class members defined by private can only be accessed by the class where the member is located.
