What are some alternative approaches to handling conditional statements in PHP for form processing?

When processing forms in PHP, handling conditional statements can become complex and clutter the code. One alternative approach is to use a switch statement instead of multiple if-else statements to improve readability and maintainability. 

// Example of using a switch statement for form processing
$action = $_POST['action'];

switch ($action) {
    case 'login':
        // Process login form
        break;
    case 'register':
        // Process registration form
        break;
    case 'update':
        // Process update form
        break;
    default:
        // Handle unknown action
        break;
}
