composer require org_heigl/filefinder

$finder = new \Org_Heigl\FileFinder\FileFinder();
$finder->addDirectory($dir);
$list = $finder->find()
$list->sort(new \Org_Heigl\FileFinder\Sorter\MTime());

$list should now be iterable, contain all files recursively within $dir sorted by their mtime…

There's also the possibility to filter or sort the files by different parameters. More info in the README
