PHP Classes & Objects

Defining a Class

class Car {
    public $brand;
    private $speed;

    public function __construct($brand) {
        $this->brand = $brand;
        $this->speed = 0;
    }

    public function accelerate($amount) {
        $this->speed += $amount;
    }

    public function getSpeed() {
        return $this->speed;
    }
}

Creating Objects

$myCar = new Car("Toyota");
$myCar->accelerate(30);
echo $myCar->getSpeed();  // 30

Inheritance

class ElectricCar extends Car {
    public function charge() {
        echo "Charging...";
    }
}
