What are the advantages of using a Mailer class like PHPMailer, Swiftmailer, or Zend_Mail over the built-in mail() function in PHP?

Using a Mailer class like PHPMailer, Swiftmailer, or Zend_Mail over the built-in mail() function in PHP offers advantages such as better support for attachments, HTML emails, SMTP authentication, and error handling. These libraries provide more robust and reliable email sending capabilities compared to the basic functionality of the mail() function. 

// Example using PHPMailer to send an email
require 'vendor/autoload.php'; // Include PHPMailer autoload file

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

// Set up the SMTP settings
$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;

// Set email content
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Test Email';
$mail->Body = 'This is a test email sent using PHPMailer.';

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