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.

まず bugs.php.net/bug.php?id=34972 の過去の議論と、php-src における既存の端末入力処理を確認します。適切な Windows のエントリーポイントと、サポート対象のオペレーティングシステム全体で 1 回のキー押下を取得する際の動作を判断します。Enter を必要とせずにキーを読み取る、文書化およびテスト済みのクロスプラットフォームな方法があれば完了です。
