Question

我有一个如下所示的数组：

Array (
    [TIMESTAMP] => 2012-01-04T21:36:32Z
    [CORRELATIONID] => 4564e64d7f75f
    [ACK] => Failure
    [VERSION] => 51.0
    [BUILD] => 2278658
    [L_ERRORCODE0] => 10764
    [L_SHORTMESSAGE0] => This transaction cannot be processed at this time. Please try again later.
    [L_LONGMESSAGE0] => This transaction cannot be processed at this time. Please try again later.
    [L_SEVERITYCODE0] => Error
    [L_ERRORPARAMID0] => ProcessorResponse
    [L_ERRORPARAMVALUE0] => PPAV
    [AMT] => 25.00
    [CURRENCYCODE] => USD
    [AVSCODE] => N
    [CVV2MATCH] => M
)

如果我想要回显[L_LONGMESSAGE0]的值（这是'此交易此时无法处理。请稍后再试'），我将如何使用php执行此操作？

更清楚的是，当我使用此命令时，我从PayPal获取此数组： urldecode（print_r（$ httpParsedResponseAr，true））

因此，假设该命令产生上面显示的数组，我将如何回显[L_LONGMESSAGE0]？

提前感谢您的帮助

Answer 1

假设：此数组位于$arr变量内。

echo $arr['L_LONGMESSAGE0'];

Answer 2

echo $myarray["L_LONGMESSAGE0"]

Answer 3

如果你的数组存储在变量$ response中，你可以

echo $response["L_LONGMESSAGE0"];

Answer 4

有点偏离主题，但我希望你不会向买家提供这些信息？ API错误响应应由您（商家）解释，并向买方显示更友好的消息至少，您可以进行简单的切换;

switch ($httpParsedResponseAr['L_ERRORCODE0']) {
        case "10764":
            echo "Unable to process your transaction. Please try a different payment method.";
            break;
        case "10002":
            echo "Unexpected error. Please try again in an hour.";
            // Log error
            error_log("10002 error in site",1,"operator@example.com");
            break;
        case "10001":
            echo "Unexpected error from PayPal. Our engineers have been notified.";
            error_log("10001 in site",1,"operator@example.com");
            break;
    }
