What are the benefits of using a dedicated Mailer class instead of the mail() function in PHP for sending emails?

Using a dedicated Mailer class instead of the mail() function in PHP for sending emails provides several benefits such as better code organization, easier maintenance, and improved testability. The Mailer class can encapsulate all email-related functionality, making it easier to manage and reuse across different parts of the application. 

class Mailer {
    public function sendEmail($to, $subject, $message) {
        // Code to send email using a more advanced mailing library like PHPMailer or Swift Mailer
    }
}

// Example of how to use the Mailer class
$mailer = new Mailer();
$mailer->sendEmail('recipient@example.com', 'Test Email', 'This is a test email message.');
