What are the advantages of using a Mail Class like phpmailer or swiftmail over the traditional mail() function in PHP?

When sending emails in PHP, using a Mail Class like phpmailer or swiftmail offers several advantages over the traditional mail() function. These libraries provide more advanced features such as SMTP authentication, HTML email support, attachments, and better error handling. They also offer better security measures to prevent email header injection and spam. Overall, using a Mail Class can make the process of sending emails more reliable and efficient. 

// Example using PHPMailer
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your-email@example.com';
    $mail->Password = 'your-password';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    $mail->isHTML(true);
    $mail->Subject = 'Subject';
    $mail->Body = 'Email body';

    $mail->send();
    echo 'Email sent successfully';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
