我需要通过getNotifications函数中的值’start_date’DESC顺序对通知数组进行排序:
$posts_id_arr = getPoststIds($conn); foreach ($posts_id_arr as $key => $val) { $total_arr[$key] = [ 'notification' => getNotifications($val['post_id'],$user_id,$conn) ]; } $response_array = array('data' => $total_arr,'more things' => $more_array); echo json_encode($response_array);
现在由于foreach循环,订单是post id.
data { notification: [ { post_id: “1",start_date: "2016-10-10 08:00:00",},{ post_id: “1",start_date: "2016-10-10 12:00:00",} ],notification: [ post_id: “2",start_date: "2016-10-10 09:00:00",{ post_id: “2",start_date: "2016-10-10 13:00:00",} ] }
我需要它是1:08:00,2:09:00,1:12:00,2:13:00
