使用PHP循环到数组数组

Question

我有这个数组，

$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'
        )
    )
)

我正在寻找使用PHP循环到days数组。

请问怎么可能？

感谢您的帮助。
