我需要获取数组的值

Question

我的数组结构是

Array
(

    [customer_id] => Array
        (
            [0] => Array
                (
                    [customer_id] => 123
                )
        )
    [menu_item_net_price] => 1700
    [menu_item_tax_price] => 4%
    [menu_item_gross_price] => 1700
    [provider_id] => 123
)

我需要得到的价值[customer_id] => 123.告诉我该怎么做？

仍然我的问题没有解决,所以我发布代码:

$data['customer_id'] = $this->session->userdata('id');
            $data['menu_item_net_price']= $netPrice;
            $data['menu_item_tax_price']= '4%'; 
            $data['menu_item_gross_price']= $netPrice;
            $data['provider_id']= 123; 
            echo '<pre>';
            print_r($data);
            echo '</pre>';
            exit(0);

Answer 1

echo $data['customer_id'][0]['customer_id'];
