What is the use of polymorphism in 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 the use of polymorphism in programming?
“In programming languages and type theory, polymorphism is the provision of a single interface to entities of different types, or the use of a single symbol to represent multiple different types.” Polymorphism is essential to object-oriented programming (OOP).
Is polymorphism supported in PHP?
In general terms, polymorphism is derived from Greek words poly meaning many and morphism meaning forms. 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.
What is compile-time polymorphism?
Compile Time Polymorphism: Whenever an object is bound with their functionality at the compile-time, this is known as the compile-time polymorphism. So this is called compile-time polymorphism or static or early binding. Compile-time polymorphism is achieved through method overloading.
What is compile time polymorphism and runtime polymorphism?
In Compile time Polymorphism, the call is resolved by the compiler. In Run time Polymorphism, the call is not resolved by the compiler. 2. It is also known as Static binding, Early binding and overloading as well. It is also known as Dynamic binding, Late binding and overriding as well.
What is runtime polymorphism and compile time polymorphism?
Why polymorphism is used in oops?
Polymorphism is one of the most important concept of object oriented programming language. The most common use of polymorphism in object-oriented programming occurs when a parent class reference is used to refer to a child class object. Here we will see how to represent any function in many types and many forms.
What is polymorphic call in PHP?
Polymorphism describes a pattern in object oriented programming in which classes have different functionality while sharing a common interface. The beauty of polymorphism is that the code working with the different classes does not need to know which class it is using since they’re all used the same way.
What is the advantage of runtime polymorphism?
The main advantage of Runtime Polymorphism is the ability of the class to offer the specification of its own to another inherited method. This transfer of implementation of one method to another method is possible without changing or modifying the codes of the parent class object.
How polymorphism is achieved at compile time and runtime?
Compile Time Polymorphism: The compile time polymorphism can be achieved by function overloading or by operator overloading. The overloaded functions are invoked by matching the type and number of arguments and this is done at the compile time so, compiler selects the appropriate function at the compile time.
