The correct behavior that is consistent with the API follows(that I am
planning):
Set retval of socket_select() to be the number of file descriptors
available. If error occurs set to false.
Using the c-api one commonly writes code like this
--------------------------------------------------
Error on an actual error or no sockets available:
ret=select(rfds, NULL, NULL, &tv);
if (ret < 0)
error_func();
Error differently:
ret=select(rfds, NULL, NULL, &tv);
if (ret == -1)
error_sys();
if (ret == 0)
error_noavail();
The equiv in php using false:
------------------------------
Error on an actual error or no sockets available:
$ret=socket_select($rfds, NULL, NULL, 1);
if (ret == 0)
error_func();
Error differently:
$ret=socket_select($rfds, NULL, NULL, 1);
if (ret === FALSE)
error_sys();
if (ret === 0)
error_noavail();

Yes, the goal is to follow a more php like behavior. Those who follow
the C-API will have some slight adjusting to, but the beauty of the
high-level language is that we can automate and simplify the
functionality.
This also makes it easier for people who don't know C to pickup the
functionality.
