Are there any best practices for incorporating progress indicators in PHP scripts for database restores?

When performing database restores in PHP scripts, it is helpful to incorporate progress indicators to keep users informed about the status of the restore process. One way to achieve this is by using AJAX requests to periodically update a progress bar on the front end. This can be done by tracking the progress of the restore operation in the PHP script and sending updates to the front end as the restore progresses. 

<?php
// Track progress of database restore operation
$totalSteps = 100; // Total number of steps in the restore process
$currentStep = 0; // Current step of the restore process

// Simulate restore process
while ($currentStep < $totalSteps) {
    // Perform restore operation for current step
    
    // Update progress bar on front end using AJAX
    echo "<script>updateProgressBar(" . ($currentStep / $totalSteps * 100) . ");</script>";
    
    // Increment current step
    $currentStep++;
    
    // Simulate delay
    sleep(1);
}

// Restore process completed
echo "<script>updateProgressBar(100);</script>";
echo "Database restore operation completed!";
?>
