What are the advantages of using mailer classes like Swiftmailer or PHPMailer for sending emails in PHP applications?

Using mailer classes like Swiftmailer or PHPMailer in PHP applications offers several advantages over using the built-in `mail()` function. These classes provide a more object-oriented approach to sending emails, making it easier to customize and format emails. They also offer better support for attachments, HTML emails, and SMTP authentication, which can improve deliverability and security. 

// Example using PHPMailer to send an email
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

// Include the PHPMailer autoload.php file
require 'vendor/autoload.php';

// Create a new PHPMailer instance
$mail = new PHPMailer();

// Set up the SMTP settings
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'yourpassword';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// Set the email content
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('to@example.com', 'Recipient Name');
$mail->Subject = 'Test Email';
$mail->Body = 'This is a test email sent using PHP';

// Send the email
if(!$mail->send()) {
    echo 'Email could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Email has been sent';
}
