Question

以下是我的返回页面的代码。它运行良好并成功完成。我假设，由于页面成功，因此$ requestParams中的变量在页面上可用。在$ requestParams

中显示变量值的正确语法是什么

<?php
require_once '../library/DPayPal.php'; //Import library


$token=$_GET["token"];//Returned by paypal, you can save this in SESSION too
$paypal = new DPaypal();
$requestParams = array('TOKEN' => $token);

$response = $paypal->GetExpressCheckoutDetails($requestParams);
$payerId=$response["PAYERID"];//Payer id returned by paypal

//Create request for DoExpressCheckoutPayment
$requestParams=array(
    "TOKEN"=>$token,
    "PAYERID"=>$payerId,
    "PAYMENTREQUEST_0_AMT"=>"20",//Payment amount. This value should be sum of of item values, if there are more items in order
    "PAYMENTREQUEST_0_CURRENCYCODE"=>"USD",//Payment currency
    "PAYMENTREQUEST_0_ITEMAMT"=>"20"//Item amount
);
$transactionResponse=$paypal->DoExpressCheckoutPayment($requestParams);//Execute transaction

if(is_array($transactionResponse) && $transactionResponse["ACK"]=="Success"){//Payment was successfull

echo "Successfull";

//  Displays Successfull, but NONE of the following commands display any results


print_r($transactionResponse["PAYMENTREQUEST_0_CURRENCYCODE"]);
echo $transactionResponse["PAYMENTREQUEST_0_CURRENCYCODE"];

print_r($transactionResponse);
echo $transactionResponse;
}



else{

echo "Failed";
}

?>

Answer 1

如果您只是需要查看转出的数据供您自己参考，您可以使用$ transactionResponse执行相同的操作。如果您想显示用户的值，可以看到您可以这样做。

foreach($requestParams as $var => $val)
{
    echo $var . ': ' . $val . '<br />';
}
