Ran the latest bug script on my home computer. I did not encounter the error. The output:
C:\PHP56>php bug.php

Since this is 5.6.13 and not 5.6.12, I'm going to download a copy of 5.6.12 to see if I can
recreate this issue. If not, I am going to try to identify what is happening on my work system as I
have seen a few similar errors and I'm wondering if they are antivirus related.

Updated test script:
<?php
$timeout = 15;
$socket = fsockopen("www.google.com",80,$errno,$errstr,$timeout);
var_dump($socket);
if(!$socket) {
echo "Error: bad socket\n";
}
else {
fwrite($socket, "GET / HTTP/1.0\r\n\r\n");
echo fgets($socket);
fclose($socket);
}
echo "<br>\n";
$socket = fsockopen("www.google.com",80,$errno,$errstr,$timeout);
var_dump($socket);
if(!$socket) {
echo "Error: bad socket\n";
}
else {
$sock_r = null;
$sock_w = array($socket);
$sock_e = null;
$result = stream_select($sock_r,$sock_w,$sock_e,$timeout);
var_dump($result);
fwrite($socket, "GET / HTTP/1.0\r\n\r\n");
echo fgets($socket);
fclose($socket);
}

I uninstalled the Security Suite software to ensure it was not related to that. Still have the same
issue.
If this is an environment issue, what things should I be looking for?
I will also take a copy of this home and test it there.

Hi,
I don't reproduce this. Probably need a more reliable reproduce case, or you should check your
environment. In the PHP code, checking that the returned socket is valid before select should be
done, too.
Thanks.

Description:
------------
Using stream_select on Windows generates a warning:
Warning: stream_select(): unable to select [2]: No such file or directory (max_fd=1168) in
C:\path\x.php on line 8
Should not create an error. Note that fd changes per iteration. Error exists using both CLI and
Apache php5apache2_4.dll.
Test script:
---------------
<?php
$timeout = 15;
$socket = fsockopen("www.google.com",80,$errno,$errstr,$timeout);
fwrite($socket, "GET / HTTP/1.0\r\n\r\n");
echo fgets($socket);
fclose($socket);
echo "<br>";
$socket = fsockopen("www.google.com",80,$errno,$errstr,$timeout);
$sock_r = null;
$sock_w = array($socket);
$sock_e = null;
$result = stream_select($sock_r,$sock_w,$sock_e,$timeout);
if ($result !== false) {
fwrite($socket, "GET / HTTP/1.0\r\n\r\n");
echo fgets($socket);
}
fclose($socket);
?>
Expected result:
----------------
HTTP/1.0 200 OK
<br>
HTTP/1.0 200 OK
Actual result:
--------------
HTTP/1.0 200 OK
Warning: stream_select(): unable to select [2]: No such file or directory (max_fd=1352) in
C:\path\x.php on line 15
