Mainly, overriding is NOT possible in same class otherwise. The code above overrides toString() method of Object class. Now also it is overriding a superclass method and here the super class is Object which is the super class of all classes.
What is PHP trait?
Traits are a mechanism for code reuse in single inheritance languages such as PHP. A Trait is intended to reduce some limitations of single inheritance by enabling a developer to reuse sets of methods freely in several independent classes living in different class hierarchies.
Why constructor is used in PHP?
A constructor allows you to initialize an object’s properties upon creation of the object. If you create a __construct() function, PHP will automatically call this function when you create an object from a class.
What is __ call () in PHP?

What is polymorphism PHP?
Polymorphism allows objects of different classes to respond differently based on the same message. To implement polymorphism in PHP, you can use either abstract classes or interfaces. Polymorphism helps you create a generic framework that takes the different object types that share the same interface.
What is name space in PHP?
A namespace is a hierarchically labeled code block holding a regular PHP code. A namespace can contain valid PHP code. Namespace affects following types of code: classes (including abstracts and traits), interfaces, functions, and constants. Namespaces are declared using the namespace keyword.
What is overloading and overriding?
Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding occurs when two methods have the same method name and parameters. One of the methods is in the parent class, and the other is in the child class.
What is Overriding in OOP?
Overriding is an object-oriented programming feature that enables a child class to provide different implementation for a method that is already defined and/or implemented in its parent class or one of its parent classes. … Overriding enables handling different data types through a uniform interface.
What is Overriding in C++?
Function overriding in C++ is a feature that allows us to use a function in the child class that is already present in its parent class. … Function overriding means creating a newer version of the parent class function in the child class.
What is Overriding in Java?
In any object-oriented programming language, Overriding is a feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its super-classes or parent classes. … Method overriding is one of the way by which java achieve Run Time Polymorphism.
