循環到數組的數組用PHP

Question

我有這樣的陣列，

$bookings[] = array(
    'booking_id' => '1', 
    'client_name' => 'John', 
    'client_firstname' => 'Peter', 
    'days' => array(
     array(
      'day_id' => '2016-11-23', 
      'room_id' => '2' 
     ), 
     array(
      'day_id' => '2016-11-24', 
      'room_id' => '2' 
     ), 
     array(
      'day_id' => '2016-11-25', 
      'room_id' => '4' 
     ) 
    ) 
) 

我在尋找循環到days數組用PHP。

請問怎麼可能？

感謝您的幫助。
