How can the separation of business logic from presentation logic improve code structure in PHP?

Separating business logic from presentation logic in PHP can improve code structure by making the code more modular, easier to maintain, and promoting better separation of concerns. This separation allows developers to focus on specific tasks without mixing different responsibilities in the same codebase. 

// Business Logic (in a separate file or class)
class User {
    public function getUserData($userId) {
        // Fetch user data from database
        return $userData;
    }
}

// Presentation Logic
$user = new User();
$userData = $user->getUserData($userId);
// Display user data in HTML
echo "<p>Name: " . $userData['name'] . "</p>";
echo "<p>Email: " . $userData['email'] . "</p>";
