What are the advantages of using PHPMailer or Swift Mailer over PHP's mail() function for sending emails?

When sending emails in PHP, using PHPMailer or Swift Mailer libraries over the built-in mail() function provides advantages such as better error handling, support for attachments, HTML emails, SMTP authentication, and more robust security features. These libraries offer a more reliable and flexible way to send emails compared to the basic functionality provided by mail(). 

// Example using PHPMailer library to send an email
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 = 'tls';
    $mail->Port = 587;

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

    $mail->isHTML(true);
    $mail->Subject = 'Subject of the email';
    $mail->Body = 'This is the HTML message body';

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