How can PHP be used to dynamically generate and send HTML emails?

To dynamically generate and send HTML emails using PHP, you can use the PHP `mail()` function along with setting appropriate headers for the email content type. You can create an HTML template for the email content and use PHP variables to inject dynamic data into the email before sending it.

<?php
$to = 'recipient@example.com';
$subject = 'Subject of the Email';
$message = '<html><body>';
$message .= '<h1>Hello!</h1>';
$message .= '<p>This is a dynamically generated HTML email.</p>';
$message .= '</body></html>';

$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";
$headers .= 'From: sender@example.com' . "\r\n";

mail($to, $subject, $message, $headers);
?>
