Q:

What type of inheritance that PHP supports? Provide an example.

Answer

PHP supports single level inheritance.


Inheriting a class would mean creating a new class with all functionality of the existing class in addition to some more. The created class is called as a subclass of the parent class. Parent is a keyword which we use to access members of a parent class. Inheritance is usually defined by using the keyword “Extend”. $this is used a reference to the calling object. Inheritance avoids redundancy of code.


Example:


Class employee extends manager : Here Employee is a subclass of manager.


Echo $this->name can be used to echo variable name of the parent class.
