Ping?

[Anon]

this one should work, but dosen't. ;-(

function ping($host) {
$ip=gethostbyname($host);
$result=ping -c 1 $ip;
$a=strpos($result, "time=");
$b=strpos($result, " ms");
if (!$a || !$b) {
return FALSE;
}
$a=$a+5;
$r=substr($result, $a, $b-$a);
return $r;
}

dosen't work on my windows-maschine.
there is no data in $result.
i tried many other ways but none worked.
is there an option to turn on in php?
or dosen't it work on windows?

tnx Wolf

ps: excuse my BAD english. i'm german.

The backsticks-operator runs a shell-command, so windows might not return anything on ping -c 1 $ip, I see that as the most likely error in the script. (try running: ping --help in command.com)
But on top of that, it's not very likely that windows will return the same ping-result-syntax as Linux, so you'll have to check the syntax for ping in DOS.
Älso be aware that gethostbyname() has a quite long timeout, in case the host doesn't exist and you are not able to tweak that timeout, at least not that I know of...
Try searching http://php.net for "gethostbyname" in the functions-db.
Well, that's what I think could be buggy in your script concerning windows...
Good luck tweaking it...

i wouldn\'t use the backticks but rather popen(). look here:
