{

$dirs = array_map(function ($item) use ($directory_seperator) {
    return $item . $directory_seperator;
}, array_filter(glob($directory . '*'), 'is_dir'));

foreach ($dirs AS $dir) {
    $dirs = array_merge($dirs, getAllDirs($dir, $directory_seperator));
}
return $dirs;
}



function getAllImgs($directory)
 {
  $resizedFilePath = array();
  foreach ($directory AS $dir) {

    foreach (glob($dir . '*.jpg') as $filename) {

        array_push($resizedFilePath, $filename);

    }

}
  return $resizedFilePath;
}


 $directory = "C:/xampp/htdocs/images/";
 $directory_seperator = "/";

 $$allimages = getAllImgs(getAllDirs($directory, $directory_seperator));
