Test connection ip/port from imput form

I'm trying to make a form that test connection from the input IP and port & query port here is my code. It's not working dunno why. I took some parts from other codes and put them together, can you please help me with that?

Thank you.

<?php

$host =  $_POST["adress"];
$port =  $_POST["port"];
$query_port =  $_POST["query_port"];
$timeout = 2;

$tbegin = microtime(true); 

$fp = fsockopen($host, $port, $errno, $errstr, $timeout); 

$responding = 1;
if (!$fp) { $responding = 0; } 

$tend = microtime(true);

fclose($fp);

$mstime = ($tend - $tbegin) * 1000;
$mstime = round($mstime, 2);


?>
