class MyClass2 extends MyClass Constant VisibilityAs of PHP 7.1.0, class constants may be defined as public, private, or protected. Constants declared without any explicit visibility keyword are defined as public. Example #3 Constant Declaration as of PHP 7.1.0
foo() Visibility from other objectsObjects of the same type will have access to each others private and protected members even though they are not the same instances. This is because the implementation specific details are already known when inside those objects. Example #4 Accessing private members of the same object type
__construct($foo)
The above example will output: string(5) "hello" Accessed the private method. wbcarts at juno dot com ¶ 10 years ago

Do protected methods get inherited?protected means access to the method is restricted to the same package or by inheritance. So the answer is, yes, protected methods can be overridden by a subclass in any package. By contrast, package (default) scoped methods are not visible even to subclasses that are in a different package.
What happens when a subclass inherits the protected superclass?A subclass inherits all of the public and protected members of its parent, no matter what package the subclass is in. If the subclass is in the same package as its parent, it also inherits the package-private members of the parent.
What are base class subclass and superclass?Object is the root/base of a hierarchy of classes but in many illustrations you will see the Object class shown above of all classes at the top. General the class that is derived from another class is called a subclass. The class from which it's derived is called the superclass.
What type of class can be inherited by another class but can't be instantiated directly?Abstract classes cannot be instantiated, but they can be subclassed. When an abstract class is subclassed, the subclass usually provides implementations for all of the abstract methods in its parent class.
