How can a PHP mailer class improve the efficiency and reliability of email sending functions?

Using a PHP mailer class can improve the efficiency and reliability of email sending functions by providing a more robust and feature-rich solution compared to the built-in mail() function. PHP mailer classes often include features like SMTP authentication, HTML email support, attachments, and error handling, making it easier to send emails securely and effectively. 

// Example code using PHPMailer class to send an email
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php'; // Include PHPMailer autoload file

$mail = new PHPMailer(true); // Create a new PHPMailer instance

try {
    // Server settings
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'user@example.com';
    $mail->Password = 'password';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

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

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

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