Capture keypresses on Windows

Description

Some tutorials and packages show it is possible to capture and handle keypresses on terminals, but only available on *nix systems

The example below shows a commonly see implementation.

<?php

$stdin = fopen('php://stdin', 'r');
system('stty cbreak -echo');

stream_set_blocking($stdin, false);

while (1) {
    $keypress = fgets($stdin);
    if ($keypress) {
        echo 'Key pressed: ' . $keypress . PHP_EOL;
    }
}

EDIT:
This example captures keys presses in the open terminal, except: shift, alt, control, caps lock, meta and fn

This example above does not work on Windows.
The intention is to capture a single keypress, of course, without typing enter. This would make possible things like terminal games and many command line apps, working for any O.S.

This was discussed in the past here: https://bugs.php.net/bug.php?id=34972

CMB gave some hope this would be implemented, and so, not a bug at all.

Start by reviewing the historical discussion in bugs.php.net/bug.php?id=34972 and the existing terminal input handling in php-src. Determine the appropriate Windows entry point and how single keypress capture should behave across supported operating systems. Done means a documented, tested cross-platform way to read a key without requiring Enter.
