How can the PHP and JavaScript components of the script be integrated more effectively to achieve the desired timer behavior?

The PHP and JavaScript components can be integrated more effectively by using AJAX to communicate between the two languages. This allows for real-time updates without the need for page refreshes. By sending requests from JavaScript to a PHP script that handles the timer logic, we can achieve the desired timer behavior seamlessly.

<?php
// timer.php

// Get the current time from the server
$current_time = time();

// Calculate the end time by adding 10 seconds to the current time
$end_time = $current_time + 10;

// Return the end time to the JavaScript component
echo $end_time;
?>
