Is it more efficient to use a static display or dynamic calculation for a countdown timer in PHP?

Using a dynamic calculation for a countdown timer in PHP is more efficient than using a static display. This is because a dynamic calculation updates the timer in real-time without the need for page reloads, providing a more interactive and accurate experience for users. 

<?php
$future_date = strtotime("2023-01-01 00:00:00");
$current_date = time();
$diff = $future_date - $current_date;

$days = floor($diff / (60 * 60 * 24));
$hours = floor(($diff - $days * 60 * 60 * 24) / (60 * 60));
$minutes = floor(($diff - $days * 60 * 60 * 24 - $hours * 60 * 60) / 60);
$seconds = $diff - $days * 60 * 60 * 24 - $hours * 60 * 60 - $minutes * 60;

echo "Countdown: $days days $hours hours $minutes minutes $seconds seconds";
?>
