Are there any recommended resources or tutorials for advanced PHP script coding that can help improve the functionality of the provided code snippet?

The issue with the provided code snippet may be a lack of error handling, security measures, or optimization techniques. To improve the functionality of the code, it is recommended to utilize advanced PHP features such as exception handling, input validation, and database optimization. Additionally, incorporating design patterns like MVC or dependency injection can enhance the code's maintainability and scalability. 

// Example of implementing exception handling in PHP code
try {
    // Code that may throw an exception
    $result = someFunction();
} catch (Exception $e) {
    // Handle the exception
    echo 'An error occurred: ' . $e->getMessage();
}

// Example of input validation in PHP code
$input = $_POST['input'];
if (empty($input)) {
    // Handle empty input
    echo 'Input cannot be empty';
} else {
    // Process the input
    echo 'Input received: ' . $input;
}

// Example of database optimization in PHP code
// Use prepared statements to prevent SQL injection
$stmt = $pdo->prepare('SELECT * FROM users WHERE email = :email');
$stmt->execute(['email' => $email]);
$user = $stmt->fetch();

// Use indexes and proper query optimization for faster database operations
$stmt = $pdo->query('SELECT * FROM users WHERE status = 1');
$stmt->execute();
$users = $stmt->fetchAll();
