Code

function _boost_rmdir_rf($dirname, $callback = NULL) {
  $empty = TRUE;

  // Start with an optimistic mindset
  foreach (glob($dirname . '/*', GLOB_NOSORT) as $file) {
    if (is_dir($file)) {
      if (!_boost_rmdir_rf($file, $callback)) {
        $empty = FALSE;
      }
    }
    else {
      if (is_file($file)) {
        if (function_exists($callback)) {
          if (!$callback($file)) {
            $empty = FALSE;
            continue;
          }
        }
        @unlink($file);
      }
      else {
        $empty = FALSE;

        // it's probably a symbolic link
      }
    }
  }

  // The reason for this elaborate safeguard is that Drupal will log even
  // warnings that should have been suppressed with the @ sign. Otherwise,
  // we'd just rely on the FALSE return value from rmdir().
  return $empty && @rmdir($dirname);
