How to delete .DS_Store using unlink - php

Question

I've created a simple function to delete all the files inside a folder and the folder itself.
function fn_delete_dir($dir)
{
if (is_dir($dir)) {
$dir = rtrim($dir, '/') . '/'; // add slash to end of string
$files = glob($dir . '*', GLOB_MARK);
foreach ($files as $vfile) {
if (is_dir($vfile)) {
fn_delete_dir($vfile);
} else {
unlink($vfile);
}
}
rmdir($dir);
return 1;
}
}
$dir = $_SERVER['DOCUMENT_ROOT'] . '/page/videography/images/videos/thumbs';
if (fn_delete_dir($dir)) {
echo 'all files deleted';
} else {
echo 'deletion failed';
}
This use to work on my windows machine. Since I switched to a Mac, this function fails with the msg
Warning: rmdir(/Users/xxx/Sites/page/videography/images/videos/thumbs/): Directory not empty in /Users/xxx/Sites/[age/testing.php on line 18
I did a scandir just to check if there are hidden files, and I got the following
Array
(
[0] => .
[1] => ..
[2] => .DS_Store
[3] => thumbs
)
I'm guessing that the problem is .DS_Store and/or thumbs
So, the question is how do I delete those hidden files?

Thanks to #axiac, I was able re-create the function using opendir() / readdir() / closedir()
This function is able to delete files like thumbs .DS_Store...
function fn_delete_dir($dir)
{
if (is_dir($dir)) {
$dir = rtrim($dir, '/') . '/'; // add slash to end of string
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
if ($file != "." && $file != "..") {
if (is_dir($dir . $file)) {
fn_delete_dir($dir . $file);
} else {
unlink($dir . $file);
}
}
}
closedir($dh);
rmdir($dir . $file);
return 1;
}
}
}
