Yeah, the array_values is unnecessary:
// this will resort the way the items are ordered
shuffle($filenames); // random sort
Normally a simple foreach loop would work but since you're grabbing
the first two, a slice of the array will work:
foreach(array_slice($filenames, 0, 2) as $filename) {
$files[] = "path/to/" . $filelname;
}
