  // Load the base classes first
  foreach ($files as $file) {
    $base_class_file = BACKDROP_ROOT . '/core/includes/database/' . $file;

    }
  }

  // Then load the driver classes.
  foreach ($files as $file) {
    foreach ($backends as $class => $class_file) {
      if (strpos($class, $driver) && strpos($class_file, $file)) {
        // The OS caches file_exists() and PHP caches require_once(), so
        // we'll let both of those take care of performance here.

        // Load the base file first so that classes extending base classes will
        // have the base class loaded.
        if (file_exists($class_file)) {
          require_once $class_file;
        }
