In PHP, why is it important to isolate different database operations into separate models for better code organization and reusability?

Isolating different database operations into separate models is important for better code organization and reusability because it helps to maintain a clear separation of concerns. Each model can be responsible for handling a specific set of database operations, making the code easier to understand and maintain. Additionally, by isolating database operations into separate models, it allows for better code reusability as the same model can be used in multiple parts of the application without duplicating code. 

// Example of isolating database operations into separate models

class User {
    public function getUserById($id) {
        // Database query to get user by ID
    }

    public function updateUser($id, $data) {
        // Database query to update user data
    }
}

class Product {
    public function getProductById($id) {
        // Database query to get product by ID
    }

    public function updateProduct($id, $data) {
        // Database query to update product data
    }
}

// Implementation
$userModel = new User();
$user = $userModel->getUserById(1);
$userModel->updateUser(1, ['name' => 'John Doe']);

$productModel = new Product();
$product = $productModel->getProductById(1);
$productModel->updateProduct(1, ['name' => 'Product A']);
