What are the best practices for displaying progress bars in PHP using JavaScript?

When displaying progress bars in PHP using JavaScript, it is important to ensure that the progress bar accurately reflects the progress of the task being performed. This can be achieved by sending regular updates from the PHP script to the JavaScript code, which will update the progress bar accordingly. Additionally, it is recommended to use AJAX requests to communicate between PHP and JavaScript for real-time updates. 

<?php
// PHP script to simulate a task with progress updates
$total = 100;
for ($i = 1; $i <= $total; $i++) {
    // Perform task
    usleep(50000); // Simulate processing time
    // Send progress update to JavaScript
    echo "<script>updateProgressBar($i, $total);</script>";
    flush(); // Flush output to ensure real-time updates
}
?>
