为什么我无法访问这个数组元素

Question

这是2co的多个数组我尝试获取返回值并通过电子邮件发送给管理员，但我无法访问此数组中的值。

<?php
require_once 'payment-api/Twocheckout.php';

Twocheckout::privateKey('4D67BA12-CE09-4F1D-AB20-0133F24E3472');
Twocheckout::sellerId('901249656');
Twocheckout::sandbox(true);

try {
    $charge = Twocheckout_Charge::auth(array(
        "merchantOrderId" => "123",
        "token" => $_POST['token'],
        "currency" => 'USD',
        "total" => '10.00',
        "billingAddr" => array(
            "name" => 'Testing Tester',
            "addrLine1" => '123 Test St',
            "city" => 'Columbus',
            "state" => 'OH',
            "zipCode" => '43123',
            "country" => 'USA',
            "email" => 'example@2co.com',
            "phoneNumber" => '555-555-5555'
        )
    ));

    if ($charge['response']['responseCode'] == 'APPROVED') {
        echo "Thanks for your Order!";
        echo "<h3>Return Parameters:</h3>";
        echo "<pre>";
        echo "His name" . $charge['billingAddr']['name'];
        echo "</pre>";
    }
} catch (Twocheckout_Error $e) {
    print_r($e->getMessage());
}

这就是我尝试访问此值的方式。

echo "His name" . $charge['billingAddr']['name'];

我在这里做错了什么。

我从print_r($charge);获得了什么

Array

Answer 1

使用：

$charge['response']['billingAddr']['name'];

您忘记访问response密钥。
