在子文件夹搜索中选择特定的图像名称

Question

I'm using the following code to search for all the images in all the subfolders of a directory:

        function get_images10($root) {

            $r = array();
            foreach(glob("$root/*") as $n) {
                if (is_dir($n)) {
                    $r = array_merge($r, get_images10($n));
                } else {
                   $r[] = $n;
                }
            }

            return $r;
        }

It works fine, but now I would like to limit the search only to the images that contain in their filename the suffix "thumb-". In another script I have used the following:

if ((strpos($filename,'thumb-') !== false)) {
  //some code
}

But I have no idea where to put such statement (if) in the above mentioned code. Any idea on how I could do that?

I'm assuming it's a prefix, since it ends with -. Anyway, you'd do it in the else as an elseif:

function get_images10($root) {
    $r = array();

    foreach(glob("$root/*") as $n) {
        if (is_dir($n)) {
            $r = array_merge($r, get_images10($n));
        } elseif (strpos($n, 'thumb-') !== false) {
            $r[] = $n;
        }
    }

    return $r;
}
