What additional security measures can be implemented in a PHP-based platform for managing courses and certificates to ensure maximum security for users and data?

To ensure maximum security for users and data in a PHP-based platform for managing courses and certificates, additional security measures can be implemented such as input validation, data encryption, and secure session management. 

// Input validation to prevent SQL injection and XSS attacks
$user_input = $_POST['user_input'];
$clean_input = mysqli_real_escape_string($conn, htmlspecialchars($user_input));

// Data encryption to protect sensitive information
$encrypted_data = openssl_encrypt($data, 'AES-256-CBC', $encryption_key, 0, $iv);
$decrypted_data = openssl_decrypt($encrypted_data, 'AES-256-CBC', $encryption_key, 0, $iv);

// Secure session management to prevent session hijacking
session_start();
session_regenerate_id(true);
