How can I ping a server port with PHP

Question

I want a PHP script which allows you to ping an IP address and a port number (ip:port). I found a similar script but it works only for websites, not ip:port.

<?php

function ping($host, $port, $timeout) 
{ 
  $tB = microtime(true); 
  $fP = fSockOpen($host, $port, $errno, $errstr, $timeout); 
  if (!$fP) { return "down"; } 
  $tA = microtime(true); 
  return round((($tA - $tB) * 1000), 0)." ms"; 
}

//Echoing it will display the ping if the host is up, if not it'll say "down".
echo ping("www.google.com", 80, 10);

?>

The idea is that I can type in the IP address and port number, and I get the ping response
