Answer 1

$manufacturer references to an array. Try:

echo $manufacturer['name'];

or

echo $manufacturer['manufacturer_id];

As you can see on your var_dump , your variable $products[$product['product_id']]['manufacturers'] is an array composed by three other arrays. So each iteration of your loop will assign an array to $manufacturer variable.
