Answer : Can I execute multiple SET statements in 1 SQL UPDATE statement?

sort and asort sort arrays, but DirectoryIterator is not an array, despite providing array-like access (e.g. via foreach).  Try creating an associative array from the DirectoryIterator results and sorting that, something like:

$dircontents = array();
foreach ($subdir as $filesInfo) {
  $dircontents[$filesInfo->getFilename()] = $filesInfo;
}

sort($dircontents);

foreach($dircontents as $filename => $filesInfo) {
  ...
}
