New Comment:
I can confirm this bug affects PHP 5.3.0. today at July 22 2009 almost
4 years from its submittion and still no fix.
This is very important since you can't create a really interactive CLI
application with this issue, and stops developers from choosing PHP to
theirs CLI/CMD/Console application (Although this could affect PHP-GTK
users and developers)
Hope this fix soon
Regards

I'm having the same trouble.
With php-5.3.0-beta1 on Linux it works fine, both on STDIN and on
fopen('/dev/ttyS0'). stream_set_blocking() returns true,
stream_get_meta_data() confirms, and the stream behaves as if
non-blocking.
But with php-5.2.9 on Windows 2000 it doesn't work for either STDIN or
the serial port (COM1 instead of /dev/ttyS0). stream_set_blocking()
returns false, stream_get_meta_data() shows blocking, and the streams do
in fact block. I also tried stream_set_timeout() with a tiny value, to
simulate the effect, but that also returns false and doesn't work.

on *nix it seems to be solved.
easy way to test:
php -r "stream_set_blocking(STDIN, FALSE);echo fread(STDIN, 10);"
on *nix it instantly exits. (correct behavior)
on windows it will hang for input. (incorrect behavior, it's ignoring
the non blocking setting.)
tested on 5.2.5

i also have the same problem, i've tried the latest snapshot on windows
to no avail. It works on my linux systems however.

<?php
stream_set_blocking(STDIN, FALSE);
echo fread(STDIN, 10);
?>
notice how it just sits there? (blocking) it should exit instantly with
a null echo. (same as a tcp connection where if you just do a read that
is too fast with nonblocking it never gets a chance to fetch the data.)
what is happening is that php is blocking waiting for input
(specifically enter (line ending))
problem:
if you are echoing debug information and want to use key functionality
in tandem you can't because everything is blocked till you hit enter.
