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;\"> </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>
?>
