Using PHP is REALLY REALLY simple! Just rename your .html file(s) to .php and using PHP tags make portions of the page dynamic.

Sample Script
<html>
<head><title>My 1st PHP Script</title>
<body>
Welcome, the current time is: <?php echo date("r"); ?>
</body>
</html>
Output
My 1st PHP Script Welcome, the current time is: Fri, 12 Jun 2026 16:07:29 +0000
