Description:
------------
When you use "/." as parameter for scandir function, you list the content of your drive's root in place of you server's root.

Reproduce code:
---------------
<?php

//List directories only
function list_dirs($path)
{
   $list = scandir($path);
   
   foreach ($list as $number => $filename)
   {
       if ( $filename !== '.' && $filename !== '..' && is_dir("$path/$filename") )
       {
           // Asign more readable and logic variables
           $dir = $filename;
           $url = apache_request_headers();
           

           {
               // Print Dirs with link
               print ("<a href=\"http://$url[Host]/$path/$dir\">/$path/$dir</a> <br>\n");
	       $newpath=$path . "/" . $dir;
	       list_dirs($newpath);
           }

               
       }
   }
}
   

list_dirs('/.')

?>

Expected result:
----------------
i would like to see the directories contained in the root of the server.

Actual result:
--------------
I see the directories contained in the root of the drive
