Can't understand mount point directories on Windows

Description

The following code:

<?php
var_dump(getcwd());
print_r(scandir("."));

Resulted in this output:

string(16) "R:\dreamflame.in"
PHP Warning:  scandir(.): The system cannot find the path specifi (code: 3) in Command line code on line 2

Warning: scandir(.): The system cannot find the path specifi (code: 3) in Command line code on line 2
PHP Warning:  scandir(.): Failed to open directory: No such file or directory in Command line code on line 2

Warning: scandir(.): Failed to open directory: No such file or directory in Command line code on line 2
PHP Warning:  scandir(): (errno 2): No such file or directory in Command line code on line 2

Warning: scandir(): (errno 2): No such file or directory in Command line code on line 2

But I expected directory listing instead

PHP Version

PHP 8.0.12

Operating System

Windows 11 build 22000

Commencez par reproduire l’exemple fourni avec getcwd() et scandir(".") sous Windows 11 avec PHP 8.0.12, en utilisant le chemin indiqué R:\dreamflame.in. Comparez le comportement du répertoire courant et de la liste du répertoire avec celui d’un répertoire normal ; c’est terminé lorsque scandir(".") liste le contenu attendu sans avertissements.
