How can PHP be effectively used in combination with JavaScript to achieve desired time-based features?

To achieve desired time-based features using PHP in combination with JavaScript, you can use PHP to generate the initial time values or perform server-side calculations, and then use JavaScript to handle client-side interactions and real-time updates. This allows for a seamless integration of server-side processing with dynamic client-side functionality.

<?php
// PHP code to get current time
$current_time = date("H:i:s");

// Pass current time to JavaScript
echo "<script>var currentTime = '$current_time';</script>";
?>
