With the basics out of the way, we'll now focus on object-oriented JavaScript OOJS — this article presents a basic view of object-oriented programming OOP theory, then explores how JavaScript emulates object classes via constructor functions, and how to create object instances. To start with, let's give you a simplistic, high-level view of what Object-oriented programming OOP is. We say simplistic, because OOP can quickly get very complicated, and giving it a full treatment now would probably confuse more than help.

Object-oriented JavaScript for beginners

PHP is a server-side scripting language, mainly used for web development but also used as a general-purpose programming language. Object-Oriented Programming PHP OOP , is a type of programming language principle added to php5, that helps in building complex, reusable web applications.

Class is a programmer-defined data type, which includes local methods and local variables. It is a collection of objects. Object has properties and behaviour. When class is created, we can create any number of objects to that class.

The object is created with the help of new keyword. Also look into how we can access object properties via variables. When the properties and the methods of the parent class are accessed by the child class, we call the concept has inheritance.

The child class can inherit the parent method and give own method implementation, this property is called overridden method. When the same method of the parent class is inherited we call as inherited method. Now let us see types of inheritance supported in Object Oriented Programming and corresponding Php inheritance examples. In Single Level Inheritance the Parent class methods will be extended by the child class. All the methods can be inherited.

In MultiLevel Inheritance, the parent class method will be inherited by child class and again subclass will inherit the child class method. You can think of a class as a template for making many instances of the same kind or class of object. You define a class once and then make many objects that belong to it. Objects are also known as instance. Here child class will inherit all or few member functions and variables of a parent class. For example function name will remain same but it make take different number of arguments and can do different task.

Similarly functions can also be overloaded with different implementation. First we have to define a php class, where classname should be same as filename. Here php object is the object of the Books Class.

Inheritance When the properties and the methods of the parent class are accessed by the child class, we call the concept has inheritance.

We can imagine our universe made of different objects like sun, earth, moon etc. Similarly we can imagine our car made of different objects like wheel, steering, gear etc. Same way there is object oriented programming concepts which assume everything as an object and implement a software using different objects. You can think of a class as a template for making many instances of the same kind or class of object.

It is considered to be more powerful and fast for certain tasks than the normal way of programming in PHP. OOP helps you to create and manage tasks easily. OOP is harder to understand compared to other programming techniques.

PHP is a server-side scripting language, mainly used for web development but also used as a general-purpose programming language.

The three basic components of object orientation are; Object oriented analysis — functionality of the system Object oriented designing — architecture of the system Object oriented programming — implementation of the application Object Oriented Programming Principles The three major principles of OOP are; Encapsulation — this is concerned with hiding the implementation details and only exposing the methods. The main purpose of encapsulation is to; Reduce software development complexity — by hiding the implementation details and only exposing the operations, using a class becomes easy. Protect the internal state of an object — access to the class variables is via methods such as get and set, this makes the class flexible and easy to maintain. The internal implementation of the class can be changed without worrying about breaking the code that uses the class. Inheritance — this is concerned with the relationship between classes.

In this humble author's (or not-so-humble author's) opinion, “advanced PHP” is about continuing to learn: you already know how to use PHP, and presumably.

Although the basics of PHP are easy to learn, it is the knowledge of object-oriented PHP that separates the professionals from the hobbyists.

Let's assume we have a class named Fruit.
