What are the benefits of using PHPMailer or Swift Mailer over the traditional mail() function for sending emails?

Using PHPMailer or Swift Mailer over the traditional mail() function for sending emails provides several benefits such as better error handling, support for various email protocols (SMTP, sendmail, etc.), easier attachment handling, and built-in security features like SMTP authentication and SSL/TLS encryption. 

// 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@example.com';
    $mail->Password = 'yourpassword';
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
    $mail->Port = 587;

    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');
    $mail->Subject = 'Test Email';
    $mail->Body = 'This is a test email sent using PHPMailer.';

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