What are the potential security risks of using outdated PHP code for email form submissions?

Using outdated PHP code for email form submissions can pose security risks such as vulnerabilities to cross-site scripting (XSS) attacks, SQL injection attacks, and potential data breaches. To mitigate these risks, it is essential to update the PHP code to utilize the latest security practices and sanitize user input. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = htmlspecialchars($_POST['name']);
    $email = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL);
    $message = htmlspecialchars($_POST['message']);

    // Send email using a secure method like PHPMailer
    // Example: 
    // require 'vendor/autoload.php';
    // $mail = new PHPMailer();
    // $mail->isSMTP();
    // $mail->Host = 'smtp.example.com';
    // $mail->Port = 587;
    // $mail->SMTPSecure = 'tls';
    // $mail->SMTPAuth = true;
    // $mail->Username = 'your@example.com';
    // $mail->Password = 'yourpassword';
    // $mail->setFrom('your@example.com', 'Your Name');
    // $mail->addAddress('recipient@example.com', 'Recipient Name');
    // $mail->Subject = 'Contact Form Submission';
    // $mail->Body = "Name: $name\nEmail: $email\nMessage: $message";
    // if ($mail->send()) {
    //     echo 'Message has been sent';
    // } else {
    //     echo 'Message could not be sent.';
    // }
}
?>
