OOPs Concept in PHP

OOPs Concept in PHP 

In this post, we see how important is OOPs Concept in PHP, and how it is implemented in real life, what is OOPs. Before these, we also discussed Exception And Error Handling Tutorial Registration Form Using form TagPHP Comments, Require, IncludeWhat are Operators in PHP? If you don’t know about these, then act quickly!

OOPs Concept in PHP code can now be written object-oriented starting with version 5.

The execution of object-oriented programming is quicker and simpler.

PHP What is OOP?

Programming in an object-oriented fashion is known as OOP.

While object-oriented programming involves creating objects that contain both data and functions, procedural programming involves writing procedures or functions that perform operations on the data.

Programming in an object-oriented manner has a number of benefits over procedural programming:

  • OOPs Concept in PHP is quicker and simpler to use.
  • OOPs Concept in PHP gives the programmes a clear structure.
  • OOPs Concept in PHP makes the PHP code easier to maintain, modify, and debug by encouraging the practice of DRY (Don’t Repeat Yourself).
  • OOPs Concept in PHP enables the development of fully reusable applications with less code and faster turnaround times.

Tip:-‘Donot Repeat Yourself (DRY) is a programming philosophy that aims to minimize code repetition. Instead of repeating the same codes over and over again, you should extract the ones that are common to the programme, put them in a single location, and use them.

What are Classes and Objects?

The two basic components of object-oriented programming are classes and objects.

To understand how classes and objects differ, consider the following example:

In other words, an object is an instance of a class, and a class is a template for objects.

Each object that is generated inherits the class’s behaviors and properties, although the values of the properties vary from object to object.

Object Oriented Concepts

Let’s define some keywords linked to object-oriented programming before we delve into more detail so all the keywords are described below.

  • Class:-A class is a form of data that is defined by a programmer and contains both local functions and local data. A class can be viewed as a template for creating numerous instances of a particular kind (or class) of the object.
  • Object:- An object is a unique instance of a class-defined data structure. You create numerous objects that are members of a class by first defining them. Objects can alternatively be called instances.
  • Member Variable:−Member variables are variables that are specified within a class. The class’s member functions can be used to access this data, which will be hidden from the outside world. Once an object is constructed, these variables are referred to as the object’s attributes.
  • Member function: −The functions defined inside a class are called member functions, and they are used to retrieve object data.
  • Inheritance:−It is referred to as inheritance when a class is defined by inheriting preexisting functions from a parent class. Here, a child class may inherit all of a parent class’ member functions and variables or only some of them.
  • Polymorphism:−The concept of polymorphism, which is object-oriented, allows for the usage of the same function for several purposes. For instance, the function name will not change, but it will accept varying numbers of parameters and do various tasks.
  • Overloading: −Overloading is a sort of polymorphism in which the implementations of some or all operators vary based on the types of their inputs. Similar to variables, functions can be overloaded with many implementations.
  • Data Abstraction −Data abstraction is the process of reducing a specific set of data to a condensed illustration of the whole. In general, abstraction is the process of stripping something of its characteristics in order to reduce it to its core components.
