php multidimensional array get values

Question

This is my array in php $hotels

Array
(
    [0] => Array
        (
        [hotel_name] => Name
        [info] => info
        [rooms] => Array
            (
                [0] => Array
                    (
                        [room_name] => name
                        [beds] => 2
                        [boards] => Array
                            (
                                [board_id] => 1
                                [price] =>200.00
                            )
                    )
                )
        )
)

How can I get board_id and price I have tried few foreach loops but can't get the result

foreach($hotels as $row)
{
    foreach($row as $k)
    {
        foreach($k as $l)
        {
            echo $l['board_id'];
            echo $l['price'];
        }
    }
}

This code didn't work.

This is the way to iterate on this array:

foreach($hotels as $row) {
       foreach($row['rooms'] as $k) {
             echo $k['boards']['board_id'];
             echo $k['boards']['price'];
       }
}

You want to iterate on the hotels and the rooms (the ones with numeric indexes), because those seem to be the "collections" in this case. The other arrays only hold and group properties.
