Object Inheritance

Inheritance is a well-established programming principle, and PHP makes use of this principle in its object model. This principle will affect the way many classes and objects relate to one another. For example, when you extend a class, the subclass inherits all of the public and protected methods from the parent class. Unless a class overrides those methods, they will retain their original functionality.


How can a child class have its own methods and properties?

ust as a child class can use the properties and methods of its parent class, it can have properties and methods of its own as well. However, while a child class can use the code it inherited from the parent, the parent class is not allowed to use the child class’s code. In the example given below, we will add to the child class some code of its own by adding the $style property as well as the driveItWithStyle() method:


The parent class has its properties and methods class Car { //A private property or method can be used only by the parent. private $model; // Public methods and properties can be used by both the parent and the child classes. public function setModel($model) { $this -> model = $model; } public function getModel() { return $this -> model; } }
