polymorphism in php with example

According to the Polymorphism (Greek for “many forms”) principle, methods in different classes that do similar things should have the same name. Then new object is created for the function/ method “myMethod()”. Here we discuss the what is the definition of Polymorphism and its Working along with its examples as well as Code Implementation. Method Overriding : Method overriding is one of the ways in which Php supports Runtime Polymorphism. In practical terms, polymorphism means that if class B inherits from class A, it doesn’t have to inherit everything about class A; it can do some of the things that class A does differently. Why : Polymorphism foster many good attributes in software, among other things it fosters modularity & reuse-ability & make the type system more flexible & elastic. public function calcTask1(){ Polymorphism is the ability of a property, a method or an object to take many forms. class Triangle1 extends Shap1 This package can show several ways of implementing of polymorphism in PHP. Static Polymorphism; Dynamic Polymorphism. The four basic concepts of OOP (Object Oriented Programming) are Inheritance, Abstraction, Polymorphism and Encapsulation. } In the above syntax, we made 2 classes one is normal and the other one is to extend the class but we used the same function name/method for different functionalities. { If same functions defined in parents and child class with same signature know as function overriding. The classes names are Circle1, Triangle1, and Elliipse1. ALL RIGHTS RESERVED. As JavaScript is not a type-safe language, we can pass any type of data members with the methods. Polymorphism allows the object to decide which form of the function to implement at compile-time (overloading) as well as run-time (overriding). Capsule basically encapsulate several combination of medicines. class DerivedClass11 extends BaseClass11 There are two types of polymorphism. If we consider the above example, the method run() is common in both the child objects. The word "poly" means many and "morphs" means forms. Java Polymorphism with tutorial and examples on HTML, CSS, JavaScript, XHTML, Java, .Net, PHP, C, C++, Python, JSP, Spring, Bootstrap, jQuery, Interview Questions etc. This is the example of the implementation of the Polymorphism concept with the interface help. Polymorphism is the ability of an object to take on many forms. function draw1() For example, suppose we have the function makeSound (). I use the same CoffeeMachine project as I … Polymorphism is one of the OOPs feature that allows us to perform a single action in different ways.
