i create test controller to update progressbar
/**

*/
public function progressAction(){
ob_start();
header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');
$total = 10;
for($i=0;$i<$total;$i++)
{
$percent = intval($i/$total * 100)."%";
sleep(1); // Here call your time taking function like sending bulk sms etc.
echo '<script>
parent.document.getElementById("progressbar").innerHTML="<div style=\"width:'.$percent.';background:linear-gradient(to bottom, rgba(125,126,125,1) 0%,rgba(14,14,14,1) 100%); ;height:35px;\"> </div>";

</script>';
ob_flush();
flush();
}
echo '<script>parent.document.getElementById("information").innerHTML="<div style=\"text-align:center; font-weight:bold\">Process completed</div>"</script>';
return new Response('OK '.$i);
}
run it in template
<div class="col-md-12">
<div id="progressbar" style="border:1px solid #ccc; border-radius: 5px; "></div>
<div id="information" style="border:1px solid #ccc; border-radius: 5px; "></div>
</div>
<iframe name="loadarea" src="{{ path("progressTest") }}" id="loadarea" style="display:none2;"></iframe><br />
but have pending to end of loop, then get

How i can update progressbar ?
You are most probably missing a header X-Accel-Buffering, as described in Streaming a Response section of official documentation. Basically, your FPM does not buffer anything, but NGINX does, so at the end you will get everything in a bulk.
Try setting that header to no and see it it helps.
On a side note, returning a <script> tag like this seems like running with pair of scissors. I would suggest you refactor it completely and let the client side do that graphical manipulation solely on percentage.
