格式化時間進行查詢

Laravel框架查詢：

$query_send = Send::select(DB::raw("FROM_UNIXTIME(UNIX_TIMESTAMP(created_at),'%Y-%m-%d') as riqi"))->groupBy(DB::raw("FROM_UNIXTIME(UNIX_TIMESTAMP(created_at),'%Y-%m-%d')"))->orderBy("riqi","desc")->take(10)->get();//take(10)獲取最近10條

MySQL查詢：

select FROM_UNIXTIME(UNIX_TIMESTAMP(created_at),'%Y-%m-%d') as riqi from `hx_send` group by FROM_UNIXTIME(UNIX_TIMESTAMP(created_at),'%Y-%m-%d') order by `riqi` desc limit 10
