Learn Object Oriented Programming PHP fundamentals bootcamp | Lecture-3

Object-oriented programming (OOP) is an essential concept for modern-day software development. It allows developers to build complex systems that are easy to maintain, extend, and reuse. In this regard, the Udemy course, "Learn Object-Oriented Programming PHP Fundamentals Bootcamp" is an excellent resource for beginners who want to learn OOP.

The lecture-3 of this course explains the fundamentals of OOP, including the concept of objects, classes, properties, and methods. The instructor provides real-life examples to help learners understand how these concepts work in practice. The lecture emphasizes that everything in OOP is considered as an object, and these objects are used as the building blocks of the whole programming structure.

The first step in using OOP is to create a class, which is a blueprint that describes the object. Think of a class as a design blueprint for a house. You can create multiple houses using the same blueprint, but you can also define different properties for each house to make them unique. Similarly, in OOP, you can define different properties for each object to make them unique.

Properties are like the information contained within the blueprint, and they can be set, manipulated, and updated depending on the requirements. For instance, if you're designing a car, you can define the color, model, and engine size as properties of the car object.

Methods, on the other hand, are functions wrapped within the class. They allow developers to add additional functionality and describe additional information that makes an object unique. Methods can be thought of as the tools you use to interact with an object.

Learning OOP has several benefits. First, it allows developers to write more organized, modular, and scalable code. OOP code is easier to maintain and extend, which reduces the overall cost of software development. Second, OOP promotes code reuse, which means that developers can use existing code to build new applications, saving time and effort.

The Udemy course, "Learn Object-Oriented Programming PHP Fundamentals Bootcamp," is an excellent resource for beginners who want to learn OOP. The lecture-3 explains the fundamental concepts of OOP and provides real-life examples to help learners understand how these concepts work in practice.

  • Object-oriented programming involves thinking of everything as objects.
  • Objects are building blocks of the whole programming structure.
  • The first step in using object-oriented programming is creating a class that describes the object.
  • Classes are like blueprints and contain object information that can be used to create multiple objects.
  • Properties contain information within the blueprint and can be set and manipulated while methods are functions wrapped within the class.

In this episode of the Udemy PHP Fundamentals Bootcamp, the instructor teaches how to change property values in OOP using PHP. What is covered in the episode? The instructor begins by adding new properties and methods to the original class of the car blueprint. They demonstrate how to use the use gas method to take in a value of the amount of gas used and calculate the remaining gas in the engine. By continuously accessing the use gas method, the amount of gas in the engine can be updated. Why is this important? Understanding how to change property values in OOP using PHP is essential for building efficient and scalable web applications. By using OO...
