    {       
        $this->HTML_Progress_DM(0,60,5);
    }
}

$timer = new TimerProgress();
$bar = new HTML_Progress($timer);
$bar->setAnimSpeed(100);
$bar->setStringPainted(true);          // get space for the string
$bar->setString('');                   // but don't paint it

$ui =& $bar->getUI();
$ui->setStringAttributes('width=170 height=20 valign=bottom align=center');

Loop to run the progress


do {
    $bar->display();
    if ($bar->getPercentComplete() == 1) {
        $bar->setString('All done!');
        $bar->display();
        break;   // the progress bar has reached 100%
    }
    if ($bar->getPercentComplete() == 0.25) {
        $bar->setString('Fourth part way done!');
    }
    if ($bar->getPercentComplete() == 0.5) {
        $bar->setString('Half way done!');
    }
    if ($bar->getPercentComplete() == 0.75) {
