How can the implementation of a more structured and modular approach to PHP coding practices improve the scalability and maintainability of an online shop script?

Implementing a more structured and modular approach to PHP coding practices in an online shop script can improve scalability and maintainability by making the codebase easier to understand, modify, and extend. This approach involves breaking down the code into smaller, reusable modules, organizing them in a logical manner, and using design patterns like MVC to separate concerns. 

// Example of implementing a more structured and modular approach in PHP

// index.php
<?php
require_once 'autoload.php';

$controller = new ShopController();
$controller->handleRequest();

// autoload.php
spl_autoload_register(function ($class_name) {
    include $class_name . '.php';
});

// ShopController.php
class ShopController {
    public function handleRequest() {
        $action = isset($_GET['action']) ? $_GET['action'] : 'index';
        
        switch ($action) {
            case 'index':
                $this->indexAction();
                break;
            case 'product':
                $this->productAction();
                break;
            // Add more actions as needed
            default:
                $this->errorAction();
                break;
        }
    }
    
    private function indexAction() {
        // Logic for displaying the homepage
    }
    
    private function productAction() {
        // Logic for displaying a product
    }
    
    private function errorAction() {
        // Logic for handling errors
    }
}

// Product.php
class Product {
    private $name;
    private $price;
    
    public function __construct($name, $price) {
        $this->name = $name;
        $this->price = $price;
    }
    
    public function getName() {
        return $this->name;
    }
    
    public function getPrice() {
        return $this->price;
    }
}
