Why is it recommended to use a Mailer Class instead of the mail() function in PHP for sending emails?

Using a Mailer Class instead of the mail() function in PHP is recommended because it provides a more robust and flexible way to send emails. Mailer classes often include features like SMTP authentication, HTML email support, attachments, and more. Additionally, using a Mailer Class can help improve the security of your email sending process. 

// Example of using PHPMailer library to send emails
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your@example.com';
    $mail->Password = 'yourpassword';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    $mail->isHTML(true);
    $mail->Subject = 'Subject';
    $mail->Body = 'Email body';

    $mail->send();
    echo 'Email sent successfully';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";
}
