Creating classes and objects in PHP Mocktest

A class in PHP serves as a blueprint or template for creating objects. It defines the properties and behaviors that objects of that class will have.

The class keyword is used to define a class in PHP. It precedes the class name in the class declaration.

An object in PHP is an instance of a class. It represents a specific entity with its own set of properties and behaviors.

The new keyword is used to create an object in PHP. It is followed by the class name and optional arguments to the class constructor.

Encapsulation in OOP refers to the bundling of data (attributes) and methods (behaviors) that operate on the data into a single unit, called a class. It hides the internal state of an object and only exposes the necessary functionalities through methods.

Inheritance in OOP allows a class (subclass or derived class) to inherit properties and methods from another class (superclass or base class). It promotes code reusability and enables the creation of a hierarchy of classes.

The extends keyword is used for inheritance in PHP. It allows a subclass to inherit properties and methods from a superclass.

Polymorphism in OOP allows objects of different classes to be treated as objects of a common superclass. It enables flexibility in code design by allowing methods to behave differently based on the object's type.

Inheritance allows a method in a subclass to have the same name as a method in its superclass. This is known as method overriding, where the subclass provides a specific implementation of the method.

The __construct() method in PHP is a special method used to initialize object properties or perform any necessary setup when an object is created. It is automatically called when a new object is instantiated.
