What are the potential pitfalls of directly including views in PHP functions, as seen in the example provided in the forum thread?

Directly including views in PHP functions can lead to mixing presentation logic with business logic, making the code harder to maintain and test. It violates the separation of concerns principle, making it difficult to make changes to the view without affecting the function. To solve this issue, it's better to separate the view rendering logic from the business logic by using a template engine like Twig or creating separate view files. 

// Incorrect way of including views in PHP function
function displayUserDetails($user) {
    include 'user-details-view.php';
}

// Correct way of separating view rendering logic
function displayUserDetails($user) {
    // Render the view using a template engine like Twig
    $loader = new \Twig\Loader\FilesystemLoader('views');
    $twig = new \Twig\Environment($loader);
    echo $twig->render('user-details-view.twig', ['user' => $user]);
}
