Status: Analyzed
Bug Type: Sockets related
Operating System: Win98 and Win2k
PHP Version: 4.1.0
New Comment:
System: RedHat Linux
PHP 4.0.6
I'm specifying a timeout of 0.2 seconds, but the fsockopen() function
is taking as long as 3-4 seconds with slow domains (I know
www.krasnapolsky.sr to be slow). This example took about 3.6 seconds.
CODE:
echo microtime();
echo fsockopen("www.krasnapolsky.sr", 80, &$errno,
&$errstr, 0.2);
echo microtime();
echo "Error Number = $errno, Error String = $errstr";
RESULT:
0.39859300 1016822517
Resource id #1
0.04482100 1016822521
Error Number = 0, Error String =
So the socket is opened -- it just took way longer than I intended to
allow it.

The Win32 code does not set a timeout. The comment at the end refers to
there being a problm on linux, which I could not reproduce.
Winsock does support non-blocking IO, but is set up quite differently
than BSD sockets.

The timeout doesn't work if the host don't respond on the
requested port :-(
os: linux redhat 7.2
php 4.0.6-7
apache 1.3.20-16

well, me too!
os: win xp professional
apache 1.3.22
php 4.1.1 (win32)
the code:
$fp = fsockopen($hname,139, &$errno, &$errstr,3);
if(!$fp) echo "$hname is not responding on port 139 ";
else {
echo "$hname is alive";
fclose($fp);
}
the problem:
the 3 secs timeout does not work

ok to clarify.. seems like this is a common mistake
fsockopen() times out ok if the server doesn't exist. The problem
occurs when the server doesn't understand what is sent to it afterwards
and stalls for a reply (ie, if the port is now used by another
service).
I'll check the bugs for fwrite(), fgets() etc

A simple query to a server with fsockopen() won't timeout if the
requested server is
down.
$serverquery = fsockopen($host, $port, &$errno, &$errstr, $timeout);
The operation times out first (120 seconds), even if $timeout is as low
as 1 second; it
works fine if I remove unavailable servers from the query list.
Sometimes the server
crashes if I try the function again before the last operation times
out.
