What are the advantages of using a mailer class over the raw PHP mail() function for handling email sending in PHP?

Using a mailer class over the raw PHP mail() function provides advantages such as better error handling, support for sending HTML emails, easier attachment handling, and the ability to easily switch between different email transport methods (e.g., SMTP, sendmail). This can lead to more reliable and flexible email sending functionality in PHP applications. 

// Example of using a mailer class (Swift Mailer) to send an email in PHP
require_once 'vendor/autoload.php'; // Include the Swift Mailer library

// Create the Transport
$transport = new Swift_SmtpTransport('smtp.example.com', 587, 'tls');
$transport->setUsername('your_smtp_username');
$transport->setPassword('your_smtp_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.org', 'other@domain.org' => 'A name'])
  ->setBody('Here is the message itself');

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

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