Why is it recommended to use a Mailer class instead of the mail() function in PHP?

Using a Mailer class instead of the mail() function in PHP is recommended because it provides a more object-oriented approach to sending emails. This allows for better code organization, easier maintenance, and the ability to easily switch between different email sending methods (e.g., SMTP, sendmail). Additionally, Mailer classes often come with built-in features such as email templating, attachment handling, and error handling. 

<?php
// Example of using a Mailer class to send an email
class Mailer {
    public function sendEmail($to, $subject, $message) {
        // Code to send email using a preferred method (e.g., SMTP)
        echo "Email sent to $to with subject: $subject and message: $message";
    }
}

// Example usage
$mailer = new Mailer();
$mailer->sendEmail("recipient@example.com", "Hello", "This is a test email");
?>
