อยากรู้เกี่ยวกับ Host ที่รองรับฟังชั่น socket ได้อ้ะครับ

if($config->Socket == 1)
{
  
	$fp = fsockopen('udp://' . $config->ServerIP, $config->Port, $errno, $errstr);                        

	if (!$fp)
	{
		die();
		$unavi =  '<td>Server: <font color="#EC180F">Offline</font></td>'; 
		$plr_count     = 0;
		return FALSE;
	}
	else
	{ 
		socket_set_timeout($fp, 1); 
    		$packet = 'SAMP';
    		$packet .= chr(strtok($ip, '.'));
  		$packet .= chr(strtok('.'));
       		$packet .= chr(strtok('.'));
       		$packet .= chr(strtok('.'));
       		$packet .= chr($port & 0xFF);
       		$packet .= chr($port >> 8 & 0xFF);
		fwrite($fp, $packet.'i');
       		fread($fp, 11);   
		$is_passworded = ord(fread($fp, 1));
		$plr_count     = ord(fread($fp, 2));
  		$max_plrs      = ord(fread($fp, 2));
    		$strlen        = ord(fread($fp, 4));
    		$hostname      = fread($fp, $strlen);
    		$strlen        = ord(fread($fp, 4));
		$gamemode      = fread($fp, $strlen);
	
      		$unavi = '
	   		<td><font color="#FFFFFF">Server:</font> <font color="#20D020">Online</font></td>
	   		<td><font color="#FFFFFF">Players Online: '.$plr_count.' / '.$max_plrs.'</font></td>
	   		<td><font color="#FFFFFF">GM: '.$gamemode.'</font></td>';
	}
}
else
{
	$plr_count = 0;
	$unavi = '<td><font color="#FFFFFF">Server:</font> <font color="#20D020">'.$config->ServerIP.':'.$config->Port.'</font></td>';
}
