Woocommerce Booking - Get a specific value from “D

I have this array, that is dumped from WooCommerce using these lines:

$items = $woocommerce->cart->get_cart();
foreach($items as $item => $values) { 
    // some code here…
}

If I make a raw output of my cart ($items) and I get this:

["f584d8671586d336d84e8cf9ed43303c"]=> array(11) {
    ["booking"]=> array(15) {

    }
}

I would like to use specific data values in some php variables, and I don't find the right way to achieve this…

How can I do to get the specific value from ["wc_booking_has_resources"]?

Thanks

FIRST — Try first this (but I am unsure as I think it can be an object, so may be it will not work):

echo $items[0]['data']['wc_booking_has_resources'] . '<br>';

SECOND — With a foreach loop it will work certainly:

$items = WC()->cart->get_cart();

foreach($items as $item) { 
    $item_data = $item['data'];
}

// displaying the value for test
echo 'Booking has ressources: ' . $item_data['wc_booking_has_resources'];

// or may be this one (as $item['data'] is an object)
echo 'Booking has ressources: ' . $item_data->wc_booking_has_resources;

One of these will work, for sure…

How to get The booking try one of these:

// first (very unsure of this one)
$item_data =  $items[0]['data']['id'];

echo $item_data['id'] . '<br>'; // not sure this one work

Using a for each loop it will be much better:

$items = WC()->cart->get_cart();

foreach($items as $item) { 
    $item_data = $item['data'];
}

// As $item['data'] is an object
$booking_has_resources = $item_data->booking_has_resources;

// displaying
echo 'Booking has ressources: ' . $booking_has_resources;

This should work
