What are the potential pitfalls of using raw mail() function for sending emails in PHP, and why is it recommended to use a mailer class like SwiftMailer instead?

Using the raw mail() function in PHP for sending emails can lead to issues such as lack of proper error handling, vulnerability to header injections, and difficulty in managing attachments and HTML content. It is recommended to use a mailer class like SwiftMailer as it provides a more robust and secure way to send emails with features like error handling, attachment support, and protection against header injections. 

// Using Swift Mailer to send emails in PHP

require_once 'path/to/vendor/autoload.php';

// Create the Transport
$transport = new Swift_SmtpTransport('smtp.example.org', 25);

// 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')
  ->addPart('<q>Here is the message body</q>', 'text/html');

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

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