What alternative technologies can be used in conjunction with PHP to create interactive elements like progress bars?

To create interactive elements like progress bars in conjunction with PHP, alternative technologies such as JavaScript can be used. JavaScript can be used to dynamically update the progress bar based on the data received from PHP. By using AJAX requests to fetch data from PHP scripts, JavaScript can update the progress bar in real-time without the need to refresh the entire page.

<?php
// PHP script to calculate progress percentage
$progress = 50; // Example progress value

echo $progress; // Output progress value
?>
