fsockopen() on UDP ?? can it be done ??

[Anon]

Hi there ....

I have just made a scripts/database where
people can sign-in if they are running some king of gameserver ( CS,Q3,Q2 and etc. ) but the real problem i my "Scan server script"

The script uses : fsockopen(), and it can
eg. connect to my webserver (because it uses tcp) but i cant connect to my Gameservers

Any one got an answer or someking of an trick ???? plz .... need help bigtime 😉

Yes. Go to the "fsockopen" page at www.php.net and see the UDP example. fsockopen(udp://hostname, portnumber). I tried it on both php3 & php4. The manual says that it works on php3&php4, but it only works for me on php4.

I was trying to do the same thing. I can connect and read the first 140 bytes and then no more without the scripot hanging 🙁. This is from a CS server any ideas whats wrong? Soz not much to ur problem 🙁

Can I take a look at your script?

thanks

You certainly can and below is a cut down version, but first an explantion. THis is not the actually script thats a tad more complex but i know i having problems with this so i thought fix this bit first. The below script only read from the socket ONCE. And it works it gets the first 80 chars however if i make read from the socket more than once it hangs 🙁 i know there is more info at least 200 chars.

The stuff that is written to server makes the server respond with the info i need. If you want more info i can send u the txt file that explains it more or if u have the Half-Life SDK look at the server-protcol.txt .

<?PHP

$fp = fsockopen("udp://193.82.159.232", 27015, &$errno, &$errstr);
if (!$fp)
{
echo "ERROR: $errno - $errstr<br>\n";
}
else
{
fwrite($fp,"ÿÿÿÿdetails\x00");
$place = 5;
$got = 0;
while($got < 1)
{
$got++;
$buffer = fread($fp, 80);
print( " $got: $buffer \n ");
}
fclose($fp);
}

?>

i have deleted the script since i couldnt it to work at all and not sure it can be done in php 🙁 however i have a script that was my first try at it if u have any ideas mail me and well work something out. As for unreal q3 i guess its more than possible hopwever i dont have the rrevent SDK or information to be honest i rekon u be best of using java slightly more complex as its less abstract and you have to organise the UDP packets thu i only have a mild idea how to do it using java no idea with concern to javascript and intergrating it on a web page 🙁 btw i not sure if it works 🙁

<?PHP

$fp = fsockopen("udp://193.82.159.232", 27015, &$errno, &$errstr);
if (!$fp)
{
echo "ERROR: $errno - $errstr<br>\n";
}
else
{
fwrite($fp,"ÿÿÿÿdetails\x00");
$place = 5;
$got = 0;
$buffer = fread($fp, 120);
while($got != 12)
{
$got++;
$found = 0;
while($found != 1)
{
if($buffer[$place] == chr(0))
{
$found = 1;
}
else
{
$details[$got] .= $buffer[$place];
}
}
$place++;
print(" Detail $got : $details[$got] ");
}
fclose($fp);
}

?>

Hi again ..

No i know what you mean ... the udp-support in php doesnt work as i wanted .. so now im standing between giving up my project or
codeing the whole thing i CGI (C++) and Sockets .... but that sucks !!

Why cant the php-coders just make the udp work 😉

well if you do, make a c++ script, tell me if u get it done that is. im at uni now where i ment to learn java so i gonna try and do it in that i also got a phat bandwidth pity there all solaris boxes 🙁

[Anon]

There is a working example with full code at:
http://gameserver.dk but i couldn't get it running. The author told me udp connections don't work with php running as cgi ... but tcp connections do ... an i don't see any reason why so far.

[Anon]

Erm i'm not entirely sure why UDP wouldn't work in CGI mode. If it is so surely you can just configure it as a module? depending on the server your using. But i cant tell you if it is really the problem since i dont know where you are trying the script and what error message, if any, you get. So without that i dont think i can be of a lot of help.
