Answer 1

you can create array like this

 foreach($this->cart->contents() as $items):
                            $data_product_stock[] =  $items['id'];
                        endforeach;
                        print_r($data_product_stock);

Answer 2

Try This

array_column($data_product_stock, 'idp');

It will give array of ids but remember $data_product_stock should be array
