What are the advantages of using a Mailer class in PHP instead of directly using the mail() function, especially when dealing with complex email content?

When dealing with complex email content, using a Mailer class in PHP provides several advantages over directly using the mail() function. The Mailer class allows for easier management of email templates, attachments, HTML content, and sending emails via different transport methods (e.g., SMTP). It also provides better error handling, logging, and customization options for sending emails. 

<?php
// Example of using a Mailer class to send an email with complex content
require_once 'vendor/autoload.php'; // Include the Mailer class

// Create a new instance of the Mailer class
$mailer = new Mailer();

// Set the email content, recipients, attachments, etc.
$mailer->setSubject('Example Email');
$mailer->setBody('<p>This is an example email with complex content.</p>');
$mailer->addRecipient('recipient@example.com');
$mailer->addAttachment('path/to/file.pdf');

// Send the email using the configured transport method
if($mailer->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Failed to send email';
}
?>
