You've forgot to put the necessary styles (CSS) on your HTML document. Adds the HTML_Progress::getStyle or HTML_Progress_UI::getStyle method between style-html-tags, and your code look like:

<?php
require_once 'HTML/Progress.php';
$bar = new HTML_Progress();
?>
<style type="text/css">
<!--
<?php echo $bar->getStyle(); ?>
// -->
</style>
<?php
echo $bar->toHtml(); 
?>

The progress bar is running, but i see no changes

You've forgot to put the requires JavaScript code to manage the progress bar. Adds the HTML_Progress::getScript or HTML_Progress_UI::getScript method between script-html-tags, and your code up and running look like:

<?php
require_once 'HTML/Progress.php';
$bar = new HTML_Progress();
?>
<style type="text/css">
<!--
<?php echo $bar->getStyle(); ?>
// -->
</style>
<script type="text/javascript">
<!--
<?php echo $bar->getScript(); ?>
//-->
</script>
 
<?php
echo $bar->toHtml(); 
 
do {
    $bar->display();
    if ($bar->getPercentComplete() == 1) {
        break; // the progress bar has reached 100%
    }
    sleep(1);  // to replace by your own procedure
    $bar->incValue();
} while(1);
?>

The progress meter seems to be frozen at 100%, i see no changes

Using HTML_Progress::run rather than coding a loop as in above example, you've forgot to give a delay to progress animation. Because it's not necessary in real world, almost all cases, the delay is fixed at zero (default behaviour). Uses the HTML_Progress::setAnimSpeed method to fix the delay from 1 to 1000 milliseconds. In example below delay is only 0.5 seconds

<?php
require_once 'HTML/Progress.php';
$bar = new HTML_Progress();
$bar->setAnimSpeed(500);
?>
<style type="text/css">
<!--
<?php echo $bar->getStyle(); ?>
// -->
</style>
<script type="text/javascript">
<!--
<?php echo $bar->getScript(); ?>
//-->
</script>
 
<?php
echo $bar->toHtml(); 
$bar->run();
?>
