index.html:
<html>
<head><title>Example</title></head>
<body onload="document.getElementById('ifr').src='/script.php';">
<iframe id="ifr" style="display: none;" src=""></iframe>
<div id="output"></div>
</body>
</html>

script.php:
<html><head></head><body><?
function out($msg) {
echo '<script language="javascript"
type="text/javascript">parent.document.getElementById("output").innerHTML="'.$msg.'";</script>';
flush();
}
set_time_limit(0);
function long_ass_process($e) {
sleep(1);
}
$massive_array=array_pad(array(), 200, array());
foreach ($massive_array as $i=>$element) {
out('Processing #'.$i);
long_ass_process($element);
}
out('Done.');
