Procedural code focuses on functions and data separately. OOP groups related data and behavior, which scales better for larger apps.

Same task, two styles

// Procedural
function user_greet(string $name): string {
    return 'Hi ' . $name;

class Greeter {
    public function __construct(private string $name) {}
    public function greet(): string { return 'Hi ' . $this->name; }
}
