Make a list of friends of a member

Hello,
I want to build a table of the member's contact list (thanks to its id)
I started like that, but maybe there is a more sophisticated way of doing that?

$state = 1;	 // 1 pour les amis / -1 si la personne n'est plus amie



	$db = JFactory::getDbo();

	$query = $db->getQuery(true);

	$query->select(array('actor_id'))

		->from($db->quoteName('#__social_friends'))

		->where($db->quoteName('target_id')." = ".$db->quote($idTarget)."AND".$db->quoteName('state')." = ".$db->quote($state));

	$db->setQuery($query);

	$row = $db->loadRowList();

	// print_r ($row);

Best regards.

Eric
