Get and Set Methods

Getters and setters control access to class properties.

Example

class Product {

    private float $price;

    public function setPrice(float $price) {
        $this->price = $price;
    }

    public function getPrice(): float {
        return $this->price;
    }
}

$product = new Product();
$product->setPrice(100);

echo $product->getPrice();
