What are some tips for transitioning from procedural to object-oriented PHP programming to better understand OOP concepts?

Transitioning from procedural to object-oriented PHP programming can be challenging, but it's essential to understand OOP concepts. One tip is to start by identifying common functionalities in your procedural code and grouping them into classes. This will help you see how objects can represent real-world entities and behaviors. Additionally, practice creating classes, objects, inheritance, and encapsulation to grasp the core principles of OOP.

// Procedural code
function calculate_area($radius) {
    return 3.14 * $radius * $radius;
}

$circle_area = calculate_area(5);
echo "Circle area: " . $circle_area;

// Object-oriented code
class Circle {
    private $radius;

    public function __construct($radius) {
        $this->radius = $radius;
    }

    public function calculateArea() {
        return 3.14 * $this->radius * $this->radius;
    }
}

$circle = new Circle(5);
echo "Circle area: " . $circle->calculateArea();
