yeah it is rather undocumentated, probably because of its current
EXPERIMENTAL status.
the actual call should be this:
$timeout = array('sec' => 5, 'usec' => 0);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, $timeout);
The idea of using the blocking method and letting the read() call
to handle the time, makes you're loop simplier and not have to
manage the time elapsed.
If you want to manage the elapsed time yourself (nonblocking),
you'll have to restructure your loop because the read() will fail
if no data is available. Not to mention it will be rather
unfriendly for your cpu since you're going to have a loop that
continue to run for 5 seconds.
Another option would be to use the fsockopen/fread tools.
