I wrote a php gallery some years ago, all works fine until I put in scandir a subfolder (foto), I have the following structure:
in folder foto there are all bigger photos, inside thumbs there are all miniatures, in thumbs_b there are all medium miniatures.
The code is working fine until I keep commented the sorting arrays:
#array_multisort(array_map('filemtime', $files), SORT_NUMERIC, SORT_DESC, $files);
if I remove the comment I get a lot of errors that sounds like a issue related to path of filemtime...
array_multisort(array_map('filemtime', $files), SORT_NUMERIC, SORT_DESC, $files);
This is the error I get when try to sort images by filemtime.

and the images are not displayed anymore.
How to fix this error? Sounds me like a bug of Php. No error if I put in scandir($src_folder); without the additional path foto and if I move all images from root/gallery/foto/ to root/gallery/. The problem is sort images is not working if scandir is working on subfolder. I have php 8.1.11 64bit and apache 2.4.53 64bit.
This is a partial code, all full code is about 15 kb, this is a short version for testing purpose...

from my dropbox all files for testing purpose:
I solved by placing a function that supplies a full path for filemtime:
function filetime_callback($a, $b) {
global $src_folder;
if (filemtime($src_folder.'/foto/'.$a) === filemtime($src_folder.'/foto/'.$b)) {
return 0;
}
return filemtime($src_folder.'/foto/'.$a) > filemtime($src_folder.'/foto/'.$b) ? -1 : 1;
}
and finally I can sort my images by filemtime using a simply approach like this:
usort($files, 'filetime_callback');
The problem was that filemtime cannot find the images if are supplied in subfolder.
Thanks.
