Since you are getting some data back from the server when connecting in
this manner, everything seems to be okay. However - remember that UDP is a
connectionless protocol (unlike TCP which has a form of packet accounting),
you may not *necessarily* get all the packets delivered which may impact
finding an EOF sequence.
You may need to set a socket timeout value (use socket_set_timeout() or
stream_set_timeout() with something reasonable, say 1 second) which
continues the script if no more data is being received. Read more about
this here :
http://www.php.net/manual/en/function.fsockopen.php and
http://www.php.net/manual/en/function.socket-set-timeout.php
I have also verified that some versions of PHP (<4.2) will hang up a script
(up to the script timeout) if a packet request is blocked by a firewall on
the other end.
You can read more about this in a bug report submitted in February.
http://bugs.php.net/bug.php?id=15639
Hope it works out.

Neil Smith.

Subject: UDP packet
Hello !
I am very new to PHP so please don't laugh if my code really sucks ;=)
What i am trying to do is :
1) Opening an UDP connectión to a server (That works allright)
2) Making a query to the server (That works allright)
3) Recieve an unknow number of UDP packets with an unknown packet size (This
is my problem)
I don't know the packet size and i don't know how many packets the server
will return...
Take a look at the WHILE loop because thats where it "hangs".
If i remove the WHILE loop and just make a fread($socket,1024) it will
return some data.
My questions are as follow :
1) How can i make sure that ALL data has been recieved ?
2) Is it possible to read each UDP packet into it's own variable (array) ???
I would be very happy if someone could answer one or all question.
<?
$ip = "192.246.40.65";
$port = 27950;
$command = "˙˙˙˙getservers 60 empty full";
$data = '';
Echo "Connecting to Master Server : $ip:$port<br>";
$socket = fsockopen("udp://$ip",$port,$errno,$errstr,2);
if (!$socket)
{
echo "There was an error connecting to the Master Server<br>";
echo "Error returned was : $errorno and $errostr";
exit;
} //Socket error
else
{
echo "Connection established ..<br>";
If (!fwrite($socket,$command))
{
echo "There was an error querying the master server ..";
exit;
} //Fwrite error
echo "Query complete ..<br>";
while (!feof($socket))
{
echo "Reading data ..<br>";
$data .= fread($socket,4096);
} //End of read section
echo "$data<br>";
fclose($socket);
echo "Connection closed ..<br>";
} //End of main loop
?>

HI Niel and thanks for your answer...i will look into it.
Maybe it's a stupid question but can't i read one packet at a time and put i
into it's own variable?
or is it just a stream of data that stops when there is no more data to send
?
(I better go read something about UDP packets 8) )
I hope this understand what i am saying.

Hi,
obviously, I don't know if this is the right newsgroup to ask such
questions, but
here it goes...
what has happened with FastCGI support on the 4.3 version of PHP?
On changelog I saw that SAPI/FastCGI was discontinued.
But when I do phpinfo() it reports "Server API : CGI/FastCGI"
and when I go with "php -v" the answer is:
PHP 4.3.0 (cgi-fcgi), Copyright (c) 1997-2002 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2002 Zend Technologies
and when I go with "php -h" there's an option :
-b <address:port>|<port> Bind Path for external FASTCGI Server mode
But when I do "php -b localhost:5000" it says there's no "b" command.
What's up with FastCGI? Was it really discontinued?
If so, where can I find good alternatives to FastCGI for my home made
webserver running on WinXP and
where can I find the reasons that lead to this?
thankz
Fernando

Look for postings by Shane Caraveo on php.dev. He's been working on FastCGI
support.
