i need to get the sum of price

any ideas to do this?

Solution:

If there is relationships there is a better approach. As the data you have given you could call sum twice and make it work.

collect($array)->sum(function (array $shop) {
    return collect($shop['items'])->sum('price');
});

This will sum each individual shop and the sum amount would be the sum of each shops items.
