PS: don't rely on connect timeout of libmysql - it does not work in
every case. Check bugs.mysql.com.

Can you give more details? I'm unable to reproduce the issue with
5.3.2-dev (= should become 5.3.1). Is it possible for you to try a
snapshot? Can you provide me with a Wireshark (network sniffer)
protocol?
The connect timeout itself should work. If not, it should be a streams
or Windows matter. First question is what exactly "connect timeout"
means. A wireshark protocol should be able to tell. In 5.3.0 you may get
a successful connect within the time limit you set but then, when
reading data, experience default_socket_timeout.
Thanks!

Worked around the problem for now by testing the connection with
fsockopen prior to real_connect.

Oh but I did search and have seen #49511 propr to submitting....
#49511 mainly focuses on a query timeout and not a connection timeout,
which is my issue. MYSQL_OPT_CONNECT_TIMEOUT mentioned is unaddressed.
Also tried ini_set('default_socket_timeout', 5) as suggested in that
submission with no effect.

Description:
------------
I have a script that attempts to contact/query an MySQL server on a
LAN. If the server is available, the script runs successfully. If the
MySQL server is offline, however, the script hangs along with the
browser session indefinately. This is despite MYSQLI_OPT_CONNECT_TIMEOUT
being set to 5 seconds.
Specifically, the script below hangs when "$mysqli->real_connect" is
executed
Looking for a way to timeout connection attempt.
Running VC9 x86 Thread Safe 5.3. Default mysqli/mysqlnd php.ini
settings.
The code below worked fine in the past in the same scenario on version
5.2.8.
Reproduce code:
---------------
$mysqli = mysqli_init();
if (!$mysqli) exit(1);
if (!$mysqli->options(MYSQLI_OPT_CONNECT_TIMEOUT, 5)) {
exit(1);
}
if (!$mysqli->real_connect('localhost', 'my_user', 'my_password',
'my_db')) {
exit(1);
}
Expected result:
----------------
Quit in around 5 sec with an code 1 if MySQL is offline.
Actual result:
--------------
Script hangs indefinately and so does a browser session through which
the script is invoked. After some time (e.g. 2-5 min) the following is
logged in php_errors.log:
[23-Oct-2009 00:48:26] PHP Warning: mysqli::real_connect(): [2002] A
