Capture keypresses on Windows

[terremoth]

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.

Just for the record there is a long standing feature request for this in bug tracker as well: https://bugs.php.net/bug.php?id=34972 . We should of course leave this open as we prefer GH issues now.

Yeah, I mentioned this URL on top of the image. Thanks.

For those who are curious on how to do that on Windows, there is a Powershell way to do the exact same:

[Console]::CursorVisible = $false 

while ($true) {
    if ([Console]::KeyAvailable) { 
        $key = [Console]::ReadKey($true)  
        Write-Host "Key pressed: $($key.KeyChar)"
    }
    Start-Sleep -Milliseconds 10  # Handles excessive use of CPU
}

I am trying to make this interact with PHP
