You're missing the point, which is that windows is quirky and doesent
behave in the same way as all the other operating systems.
Now, if the same script, talking to the same hung win32 server, works
from a linux or bsd box there is no bug that we will fix (because win32
is being bad).
If it does work from another OS, we're still not likely to be able to
fix it; I've seen this kind of thing with other networking apps on
win32; the tcp/ip stack on the server gets confused and only a reboot
will fix it.
In either case, this is not something we can or will fix.

Unfortunatelly, I do not have Linux box for testing.
And to make it clear - if we have 2 machines, the only important and
relevant is machine with Windows 2000/XP server, which hosts the buggy
script.
The other machine might be anything - bug is reproductible when this
other machine has web server hanged or crashed, which makes our first
machine to hang, too!

Does it hang if you try and reach it from linux ?

Description:
------------
This bug has been reported 2 years ago, but it is still present in last
5.0.2 version.
PHP installed on Windows 2000 server or on Windows XP, all with latest
service packs. PHP run as ISAPI.
HOW TO TEST:
For destination IP $domain in my script, please use some remote machine
with IIS 5.0 or IIS 5.1.
Try the script and it should pass.
Now, on REMOTE machine, go and crash IIS service. For example, you may
crash it for sure this way:
- install PHP on remotemachine as ISAPI
- in PHP.INI enable some extension, which does not exist - try
php_pdf.dll
- start IIS and IIS should hang
Now, run the script again to test hanged IIS machine. Script should
exit with FATAL ERROR or in worst case, with IIS hang on your first
machine.
Reproduce code:
---------------
<?php
$domain = ""; //enter some IP - see instructions below!
$port = "80";
$fp = fsockopen($domain,$port,$errno,$errstr,2) ;
if (!$fp){
$output = '<br>SOCKET: '.$domain.':'.$port.' FAILED
responding!';
} else {
$output = '<br>SOCKET: '.$domain.':'.$port.' responded
OK';
fclose($fp);
}
?>
Expected result:
----------------
fsockopen() should return TRUE or FALSE, but in any case it should exit
within set TIMEOUT value (which is 2 seconds in this case).
Actual result:
--------------
In case that destination socket is IIS and it is CRASHED or HANGED, the
script will not terminate after 2 seconds, but will try open socket
until PHP timeout occures.
And additionally - in some cases, if PHP is run on IIS 5.0 or 5.1,
script may HANG and LOCK IIS so you need to restart machine. W3SVC
stops responding.
