What are the advantages of using a pre-built mailing library like PHPMailer or Swiftmailer for sending emails in PHP?

Using a pre-built mailing library like PHPMailer or Swiftmailer for sending emails in PHP can provide several advantages. These libraries offer a more robust and secure way to send emails, with built-in features such as SMTP authentication, HTML email support, attachment handling, and error handling. They also make it easier to send emails using various email services or servers without having to manually configure each one. 

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

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

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

// Set up the email parameters
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your@example.com';
$mail->Password = 'your_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

$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 could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Email has been sent.';
}
