PHP What is OOP

PHP What is OOP?

OOP stands for Object-Oriented Programming.

While procedural programming focuses on writing procedures or functions that operate on data, object-oriented programming revolves around creating objects that encapsulate both data and functions.

Object-oriented programming offers several advantages over procedural programming:

• OOP is faster and more efficient.
• OOP provides a clear and organized structure for programs.
• OOP promotes the DRY (“Don’t Repeat Yourself”) principle, making code easier to maintain, modify, and debug.
• OOP enables the creation of reusable applications with less code and reduced development time.

Tip: The “Don’t Repeat Yourself” (DRY) principle emphasizes minimizing code duplication. Extract common code into a single location and reuse it throughout your application rather than repeating it.

PHP – What are Classes and Objects?

Classes and objects are the two fundamental components of object-oriented programming.

Refer to the following illustration to understand the distinction between classes and objects:

Here’s another example:

A class serves as a blueprint for creating objects, while an object is an instance of a class.

When objects are instantiated, they inherit all properties and behaviors from the class, but each object can have distinct values for its properties.
