What are the best practices for handling email authentication and SMTP settings in PHP?

To handle email authentication and SMTP settings in PHP, it is best practice to use a library like PHPMailer which simplifies the process and provides secure authentication methods. This ensures that emails are sent securely and reliably. Additionally, setting up SMTP settings correctly is important to avoid emails being marked as spam. 

// Include PHPMailer library
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

// Instantiate PHPMailer
$mail = new PHPMailer(true);

// Set SMTP settings
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your_smtp_username';
$mail->Password = 'your_smtp_password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

// Set email content and send email
$mail->setFrom('from@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject';
$mail->Body = 'Email body content';

// Send email
if($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Email could not be sent';
}
