New to PHP? Learn the Basics of PHP OOPS


Welcome to the world of PHP! If you're new to PHP and eager to learn, you've come to the right place. In this blog post, we'll explore the fundamentals of PHP Object-Oriented Programming (OOP), a crucial aspect of modern web development. Whether you're a beginner or looking to refresh your skills, this guide will provide you with a solid foundation in PHP OOP.

Navigating the Repository

Before we dive into the basics of PHP OOP, let's take a quick tour of the repository that accompanies this guide. The repository contains a series of PHP files that demonstrate various OOP concepts and practical examples. Here's how you can navigate and make the most of the repository:

  1. Browse the Files: Start by exploring the repository's files. You'll find a collection of PHP files named according to the OOP concept they illustrate, such as inheritance, encapsulation, and polymorphism.

  2. Read the Code: Open each PHP file to read the code and comments. The code examples are accompanied by explanations that walk you through the implementation of each OOP concept.

  3. Experiment and Learn: Feel free to experiment with the code examples. Modify the code, run it locally on your machine, and observe the results. This hands-on approach will deepen your understanding of PHP OOP.

Understanding database.php and test.php

Two key files in the repository are database.php and test.php. Let's briefly discuss each one:


The database.php file contains the database connection class, which serves as the foundation for the CRUD (Create, Read, Update, Delete) operations demonstrated in the repository. This class encapsulates database connection logic using PHP OOP principles, making it reusable and easy to maintain.


The test.php file demonstrates how to perform CRUD operations using the database connection class defined in database.php. It showcases examples of:

  • Create: Inserting new records into the database.

  • Read: Fetching data from the database based on specified conditions.

  • Update: Modifying existing records in the database.

  • Delete: Removing records from the database.

Getting Started with PHP OOP

Now that you're familiar with the repository's contents and the role of database.php and test.php, let's delve into the basics of PHP OOP. We'll cover essential concepts such as classes, objects, inheritance, and more, using practical examples from the repository.


By the end of this guide, you'll have a solid grasp of the basics of PHP Object-Oriented Programming (OOP). Remember to continue practicing and exploring the code examples in the repository to reinforce your understanding. PHP OOP opens up a world of possibilities for building powerful and maintainable web applications, and with dedication and practice, you'll be well on your way to mastering it.
