How can PHP developers enhance the security and functionality of their websites by using dedicated mailer classes for sending emails?

PHP developers can enhance the security and functionality of their websites by using dedicated mailer classes for sending emails. These classes provide a more secure and reliable way to send emails, as they often include features like SMTP authentication, encryption, and error handling. By using a dedicated mailer class, developers can ensure that their email functionality is robust and protected against common security vulnerabilities. 

// Example of using a dedicated mailer class (Swift Mailer) to send emails

require_once 'vendor/autoload.php'; // Include Swift Mailer library

// Create the Transport
$transport = new Swift_SmtpTransport('smtp.example.com', 25);
$transport->setUsername('your_username');
$transport->setPassword('your_password');

// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);

// Create a message
$message = (new Swift_Message('Wonderful Subject'))
    ->setFrom(['john.doe@example.com' => 'John Doe'])
    ->setTo(['receiver@example.com' => 'Receiver Name'])
    ->setBody('Here is the message body');

// Send the message
$result = $mailer->send($message);

if ($result) {
    echo 'Email sent successfully';
} else {
    echo 'Failed to send email';
}
