How can PHP data be included in an email?

To include PHP data in an email, you can use the PHP `mail()` function to send an email with dynamic content. You can concatenate the PHP variables or data you want to include in the email message within the `mail()` function. Make sure to set the appropriate headers for the email content type and encoding.

<?php
$to = "recipient@example.com";
$subject = "Hello from PHP";
$message = "Hello, this is a message from PHP with dynamic data: " . $dynamicData;
$headers = "From: sender@example.com\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

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