function ping($host)?

Hey guys,

 

I'm trying to show a few ips are online or not, but the return is always as online. The function I'm trying to use is the one below:

<?php
function ping($host) {
	$conectado = fsockopen($host, 80, $numeroDoErro, $stringDoErro, 255);
	if ($conectado) {
		return true;
	}else{
		return false;
		fclose($conectado);
	}
}
?>

The variable $host receives an ip like this: 172.16.10.50

 

I'm calling the function like this: $ping = ping($dados[ip]);

 

I need some extra configuration to work properly?

Even pinging the host for the shell/cmd and seeing that he is inaccessible, the above function tells me that is accessible.

 

Could someone give me a light?
