使用php获取多维数组的值

Question

我想从多维数组中获取数组的值。假设我有来自API的json响应，我在php中使用json_decode（）函数解码，我想使用循环来迭代数据。

$string = $response;
$json_a = json_decode($string, true);


foreach($json_a['withdrawals'] as $item) {

    echo $item['withdrawalId']['amount']['currencyCode']. '<br/>';
    echo $item['withdrawalId']['terminal']['tid']. '<br/>';
    echo $item['withdrawalId']['user']['mid']. '<br/>';
    echo $item['servicefee']['masterMerchant']['name']. '<br/>';
    echo $item['servicefee']['masterMerchant']['address']['address1']. '<br/>';
    }
}

print_r($json_a);

这是打印出的数组。

这样写： -

$string = $response;
$json_a = json_decode($string, true);


    foreach($json_a['withdrawals'] as $item) {
        echo $item['withdrawalId']. '<br/>';

        echo $item['amount']['currencyCode']. '<br/>';
        echo $item['terminal']['tid']. '<br/>';
        echo $item['user']['mid']. '<br/>';
        echo $item['user']['masterMerchant']['name']. '<br/>';
        echo $item['user']['masterMerchant']['address']['address1']. '<br/>';
        }
    }

    print_r($json_a);
