PHP and jQuery progress bar while parsing

I was wondering how I could go about making a progress bar for parsing HTML data. Essentially the user searches something and I parse another website. I tried doing it with getting the amount of objects found in an array then dividing 100 by it, and getting the current one in a for loop and multiplying it by 100/total. Then I would update a text file with the value. Then update the progress bar with that value. However, I want a more efficient way to do it. Also it has to be unique to each user. Thanks.

I found another way to do it, this is to help all of those people that have the same question. I found it out on here http://w3shaman.com/article/php-progress-bar-script

<?php

<!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01//EN>

<html lang=en>

<head>

    <title>Progress Bar</title>

</head>

<body>

<!-- Progress bar holder -->

<div id=progress style=width:500px;border:1px solid #ccc;></div>

<!-- Progress information -->

<div id=information style=width></div>

<?php

// Total processes

$total = 10;

// Loop through process

for($i=1; $i<=$total; $i++){

    // Calculate the percentation

    $percent = intval($i/$total * 100).%;



    // Javascript for updating the progress bar and information

    echo '<script language=javascript>

    document.getElementById(progress).innerHTML=<div style=width:'.$percent.';background-color:#ddd;>&nbsp;</div>;

    document.getElementById(information).innerHTML='.$i.' row(s) processed.;

    </script>';





// This is for the buffer achieve the minimum size in order to flush data

    echo str_repeat(' ',1024*64);





// Send output to browser immediately

    flush();





// Sleep one second so we can see the delay

    sleep(1);

}

// Tell user that the process is completed

echo '<script language=javascript>document.getElementById(information).innerHTML=Process completed</script>';

?>

</body>

</html>

?>
