What are the potential security risks of directly sending form data to a webpage without storing it in a database first?

Sending form data directly to a webpage without storing it in a database first can pose security risks such as exposing sensitive information, potential data loss, and vulnerability to SQL injection attacks. To mitigate these risks, it is recommended to validate and sanitize the form data before processing it to ensure it is safe to use. 

// Validate and sanitize form data before processing
$name = isset($_POST['name']) ? htmlspecialchars($_POST['name']) : '';
$email = isset($_POST['email']) ? filter_var($_POST['email'], FILTER_SANITIZE_EMAIL) : '';
$message = isset($_POST['message']) ? htmlspecialchars($_POST['message']) : '';

// Process the sanitized form data
// Your code to handle the form data securely goes here
