What are the benefits of using a separate class or library for email handling in PHP applications?

When developing PHP applications that involve sending emails, it is beneficial to use a separate class or library for email handling. This approach helps to keep the code organized, maintainable, and reusable. It also allows for easier testing and debugging of email-related functionalities. 

// Example of using a separate class for email handling in PHP

class EmailHandler {
    public function sendEmail($to, $subject, $message) {
        // Code to send email using PHP's built-in mail function or a third-party library
    }
}

// Implementation example
$emailHandler = new EmailHandler();
$emailHandler->sendEmail('recipient@example.com', 'Subject', 'Message body');
