PHP OOP Introduction

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. But, if you understand the following 4 terms you are almost done! The first term we find in OOP is class.

Practice Tutorials. Learn how to restrict the access to your classes code by using the private and protected access modifiers. Learn how to reduce code duplication with inheritance , one of the most important concepts in object-oriented programming. Learn how to commit child classes to certain methods with abstract classes and methods. Learn about the Polymorphism naming convention that can help us write a much more coherent and easy to use code. Type hinting forces our functions to get only arguments that belong to a specific class, a specific interface, or to arrays. Home Learn Practice Blog About.

Let's assume we have a class named Fruit. A Fruit can have properties like name, color, weight, etc. When the individual objects apple, banana, etc. All its properties and methods go inside the braces:. Note: In a class, variables are called properties and functions are called methods!

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. Objects can contain related data and code, which represent information about the thing you are trying to model, and functionality or behavior that you want it to have. Object data and often, functions too can be stored neatly the official word is encapsulated inside an object package which can be given a specific name to refer to, which is sometimes called a namespace , making it easy to structure and access; objects are also commonly used as data stores that can be easily sent across the network. Let's consider a simple program that displays information about the students and teachers at a school. Here we'll look at OOP theory in general, not in the context of any specific programming language.

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.

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.

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.

Although the basics of PHP are easy to learn, it is the knowledge of object-oriented PHP that separates the professionals from the hobbyists. When using object-oriented programming, we organize the code in an efficient way, so it is easier to work with, develop and upgrade. Due to its many benefits, developers who master the craft of object-oriented PHP are a hot commodity in the job market among companies and enterprises that have a need for advanced online applications. Let's expand on the first fact as it is the most important one - everything else flows from it, i. There are great applications written in the procedural style of PHP, but even the best end up in spaghetti code where functions and variables are mixed together.

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.
