How can the Factory Pattern be effectively implemented in PHP to improve code structure and maintainability?

Issue: The Factory Pattern can be effectively implemented in PHP to improve code structure and maintainability by centralizing object creation logic in a separate factory class. This helps to decouple the client code from the concrete implementations of objects, making it easier to switch between different implementations without modifying the client code. PHP Code Snippet: 

<?php

// Interface for the product
interface Product {
    public function operation(): string;
}

// Concrete implementation of the product
class ConcreteProduct implements Product {
    public function operation(): string {
        return "This is a concrete product.";
    }
}

// Factory class to create instances of the product
class ProductFactory {
    public static function createProduct(): Product {
        return new ConcreteProduct();
    }
}

// Client code
$product = ProductFactory::createProduct();
echo $product->operation();

?>
