            $ip = trim($ip1);

            for($i=$port1;$i<$port2+1;$i++) {
                $tB = microtime(true);
                $fP = fSockOpen($ip, $i, $errno, $errstr, 1);
                $tA = microtime(true);
                if (!$fP) {
                    echo $ip.":".$i." – down";
                } else {
                    echo $ip.":".$i." – ".round((($tA – $tB) * 1000), 0)." ms";
                    fwrite($fh,$ip."
");
                }
                echo "<br>";
                flush();
            }
        }
    }
    echo '<a href="ip_up.txt">Download</a>';
}
else die('error');
?>

it gives me this error in line 20

Parse error: syntax error, unexpected T_STRING

i tried to put ' ' in line 20..but it dosend work !!

Answer 1

The problem is here:

round((($tA – $tB)

I think that you want to subtract them, so use this:

round((($tA - $tB)

It's a very minor difference, but you are not using the correct dash.
