What are the differences between sending emails using PHP's mail() function and using a Mailer class in terms of encoding and security?

When sending emails using PHP's mail() function, the emails are often sent as plain text, which can potentially expose sensitive information. On the other hand, using a Mailer class allows for better control over the encoding of the email content, ensuring that it is properly formatted and secure. Additionally, Mailer classes often provide built-in security features such as SMTP authentication and encryption. 

// Using a Mailer class for sending emails with proper encoding and security
use PHPMailer\PHPMailer\PHPMailer;

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

// Set up the necessary configurations
$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 the email content and encoding
$mail->isHTML(true);
$mail->Subject = 'Subject here';
$mail->Body = 'Email content here';

// Add recipients
$mail->addAddress('recipient@example.com', 'Recipient Name');

// Send the email
if ($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Error sending email: ' . $mail->ErrorInfo;
}
