Comment (by schlessera):

 As far as I can tell from documentation, retrieving the `fileinode` will
 always return `0` for all files on Windows for versions of PHP below 7.4.

 From https://www.php.net/manual/en/function.fileinode.php:
 > As documented in
 https://www.php.net/manual/en/function.stat.php#refsect1-function.stat-
 returnvalues:
 > On Windows, as of PHP 7.4.0, this is the identifier associated with the
 file, which is a 64-bit unsigned integer, so may overflow. Previously, it
 was always 0.
 >
 > It appears that fileinode shares the same underlying implementation.
