What are the benefits of using a mailer class instead of the raw mail() function in PHP for sending form submissions?

Using a mailer class instead of the raw mail() function in PHP for sending form submissions provides several benefits such as better error handling, easier customization of email headers and content, support for attachments, and improved security against email injection attacks. 

// Example code using a mailer class to send form submissions

require 'PHPMailer/PHPMailer.php';
require 'PHPMailer/SMTP.php';

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

// Initialize PHPMailer
$mail = new PHPMailer();
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'yourpassword';
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
$mail->Port = 587;

// Set email content
$mail->setFrom('from@example.com', 'Sender Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject of the email';
$mail->Body = 'Body of the email';

// Send the email
if ($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Email could not be sent. Mailer Error: ' . $mail->ErrorInfo;
}
