Introduction to OOP

Object-Oriented Programming (OOP) in PHP allows you to structure your code using classes and objects. It makes applications easier to scale, maintain, and reuse.

Classes & Objects

How to create PHP classes and instantiate objects.

Constructors

Constructors allow you to initialize object values automatically.

Visibility (public, private, protected)

Control access to class properties and methods.

Getters & Setters

Encapsulate private data and control access safely.

Inheritance

Allow classes to inherit behavior from parent classes.

Interfaces & Abstract Classes

Build flexible architectures and respect contracts.

Traits

Use Traits to reuse logic across multiple classes.

Namespaces & Autoloading

Organize your code and avoid naming conflicts.
