Bug #10304 Garbled Data/timeout with UDP-Socket
Submitted: 2001-04-12 11:06 UTC Modified: 2001-12-13 06:24 UTC
From: jorfen at topmail dot de Assigned:
Status: Closed Package: Sockets related
PHP Version: 4.0.4pl1 OS: Linux2.2.12
Private report: No CVE-ID: None
 [2001-04-12 11:06 UTC] jorfen at topmail dot de
function foo($ip,$port)
$fp = fsockopen("udp://".$ip,$port);
$a = fread($fp,5000);

This code is for querying a HalfLife-Server (left out if 
($fp) ...).
The script works till it tries to read from the socket. 
PHP reads a part of the string the server should return 
and hangs till the socket times out.

The same method in C, Perl etc works perfectly so I assume 
there is a problems with PHP and UDP-Sockets.

Trying to read multiple lines from a server connected to 
with an UDP-Socket give garbled Data+Timeout.

Again C, Perl work perfectly.

(recent version from CVS do not work, too)

For now, I suggest you use the sockets extensions functions:

function foo2($ip,$port)
        write($sock, "????info\x00", 11);
        close $sock;
        return $readdata;

This works for me just fine.
Seems the f-funcs don't work as expected with UDP.

Can you try with latest RC and see if it works
