How can PHP be integrated with JavaScript to achieve real-time countdown functionality?

To achieve real-time countdown functionality, PHP can be integrated with JavaScript by using AJAX to periodically fetch updated countdown values from a PHP script. The PHP script will calculate the remaining time until a specific event and return this value to the JavaScript function, which will update the countdown display on the webpage. 

<?php
// PHP script to calculate remaining time until a specific event
$eventDate = strtotime("2023-01-01 00:00:00");
$currentTime = time();
$remainingTime = $eventDate - $currentTime;

echo $remainingTime;
?>
