What are the potential pitfalls of using the PHP mail function for sending HTML emails?

The potential pitfalls of using the PHP mail function for sending HTML emails include issues with email deliverability, lack of support for advanced email features, and vulnerability to email injection attacks. To solve these issues, it is recommended to use a dedicated email library like PHPMailer or Swift Mailer, which provide better support for sending HTML emails securely and efficiently. 

// Example using PHPMailer to send HTML email
use PHPMailer\PHPMailer\PHPMailer;

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

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

// Set up the email parameters
$mail->isHTML(true);
$mail->Subject = 'Subject Here';
$mail->Body = '<h1>This is a HTML email</h1>';
$mail->addAddress('recipient@example.com', 'Recipient Name');

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