these are the sample link. my questions is how to get the group id from url? And i can't use arg(). because i have more no of url and group id position also varied.

There is any robust solutions for this.

I have used the following code in hook_preprocess_page() to solve this issue.

$url = current_path();
  $arguments = explode('/', $url);
  foreach ($arguments as $value) {
    if (is_numeric($value)) {
      $node = node_load($value);
      if (og_is_group('node', $node)) {
        drupal_set_message('group id :' . $node->nid);
      }
    }
  }

From now, i can set to group member only could see this page.
