What are the potential pitfalls of using PHP to create a user interface for Majordomo subscriptions?

One potential pitfall of using PHP to create a user interface for Majordomo subscriptions is the security vulnerabilities that may arise if proper input validation and sanitization are not implemented. To mitigate this risk, it is crucial to validate user input and sanitize data to prevent SQL injection, cross-site scripting, and other common attacks. 

// Validate user input for Majordomo subscription form
$email = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL);
if (!$email) {
    // Handle invalid email input
}

// Sanitize user input for Majordomo subscription form
$name = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$email = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);
