What is a polymorphism in PHP?
Polymorphism is one of the PHP Object Oriented Programming (OOP) features. In general, polymorphism means the ability to have many forms. If we say it in other words, “Polymorphism describes a pattern in Object Oriented Programming in which a class has varying functionality while sharing a common interfaces.”.
Does PHP support polymorphism?
Polymorphism in OOPs is a concept that allows you to create classes with different functionalities in a single interface. Generally, it is of two types: compile-time (overloading) and run time (overriding), but polymorphism in PHP does not support overloading, or in other words, compile-time polymorphism.
Why do we need polymorphism in PHP?
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. By using polymorphism, you can reduce coupling and increase code reusability.
Why is polymorphism used?
Why use Polymorphism in Java? Polymorphism in Java makes it possible to write a method that can correctly process lots of different types of functionalities that have the same name. We can also gain consistency in our code by using polymorphism.
What is overriding in PHP?
In function overriding, both parent and child classes should have same function name with and number of arguments. It is used to replace parent method in child class. The purpose of overriding is to change the behavior of parent class method. The two methods with the same name and same parameter is called overriding.
Where does the term polymorphism come from in PHP?
PHP Programming Server Side Programming To begin with, Polymorphism is gotten from the Greek words Poly (which means many) and morphism (which meaning forms). Polymorphism portrays an example in object-oriented programming where methods in various classes that do similar things should have a similar name.
What does polymorphism mean in object oriented programming?
Polymorphism is a long word for a very simple concept. Polymorphism describes a pattern in object oriented programming in which classes have different functionality while sharing a common interface.
What’s the difference between polymorphism and a morph?
The meaning of poly is “many” and morph is “forms”. It means the ability to have many forms. In common terms, Polymorphism is an Object-Oriented Programming pattern in which the class is having various functionalities while having common interfaces.
Which is a feature of object oriented programming in PHP?
The PHP programming language follows an object-oriented programming (OOP) paradigm, along with other base structures. One of the most significant features of OOPs is polymorphism. In general terms, polymorphism is derived from Greek words poly meaning many and morphism meaning forms.
