What are the advantages and disadvantages of using PHP classes for sending emails compared to the mail() function?

Using PHP classes for sending emails provides a more organized and object-oriented approach, allowing for easier maintenance and scalability of email functionality. However, it may require more initial setup and coding compared to using the simple mail() function.

<?php
// Using PHPMailer class for sending 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 = 'your_password';
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;

    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');
    $mail->isHTML(true);
    $mail->Subject = 'Subject';
    $mail->Body = 'Email body content';

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