And if I set sec=0 usec=500000 (or 5 for a shorter timeout) it hangs,
meaning to me, that usec has no effect.

Actual: Script gives timeout error but it does not wait for 5 seconds
for the answer, as set in SO_RCVTIMEO.
Expeted: to wait max. 5 second for remote host to answer, but script
executes much faster. I tried to increase second to 500000 and then it
works ok.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Description:
------------
I tried to set a receive timeout for a socket, but found out that sec
is used as usec, and usec is in fact ignored!
Reproduce code:
---------------
using a modbus device with "address" address, sorry i cannot make it
available on the net
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array("sec"=>0,
"usec"=>500));
socket_connect($socket, "address", "502");
socket_write($this->socket, $data, strlen($data));
socket_read($this->socket, 512, PHP_BINARY_READ);
Expected result:
----------------
expected to read some data or give a timeout error.
Actual result:
--------------
code hangs, so i figured out, that usec has no effect, then i tried 1
sec as timeout, code began to work, but kept reporting timeout, so i
figured out if i try a value like 500000 as sec it works. Seems like
sec is used as usec, and usec has no effect.
