What is OOP in PHP
🔷 What is OOP in PHP?
Instead of writing repeated code, OOP helps you organize code in a clean and reusable way.
🔷 Example to Understand Easily
Think about a Car.
-
A class = blueprint → tells how every car should look
-
An object = real car made from that blueprint
🔶 Why Use OOP? (Benefits)
✔ Makes code clean
✔ Makes code reusable
✔ Makes projects organized
✔ Easier to maintain & scale
✔ Used in modern frameworks like Laravel
🔷 The 4 Main Concepts of OOP
1️⃣ Class (Blueprint)
A class is a template.
Example:
2️⃣ Object (Real instance)
Object = copy created from class.
3️⃣ Inheritance
A class can get features from another class (parent → child).
4️⃣ Encapsulation
Restrict access using private, protected, public.
5️⃣ Polymorphism
Same function name, different behaviour.
6️⃣ Abstraction
Hide complex details and show only required features.
