PHP Classes & Objects

Object-Oriented Programming (OOP) lets you organize code into reusable, maintainable structures. Classes are blueprints, and objects are instances created from those blueprints!

What is a Class?

A class is a template that defines properties (data) and methods (functions) that objects will have.

Defining a Class

<?php
class Car {
    // Properties
    public $brand;
    public $color;
    
    // Method
    public function drive() {
        echo "Driving!";
    }
}
?>

Creating Objects

<?php
$myCar = new Car();
$myCar->brand = "Toyota";
$myCar->color = "red";
$myCar->drive();
?>

$this Keyword

<?php
class Car {
    public $brand;
    
    public function showBrand() {
        echo $this->brand;  // Access own property
    }
}
?>
