在 PHP 中很好地格式化 PayPal 数组

Question

我有一个从 PayPal 返回的数组：

Array
(
    [responseEnvelope.timestamp] => 2010-09-07T23%3A06%3A33.737-07%3A00
    [responseEnvelope.ack] => Success
    [responseEnvelope.correlationId] => b9d9ca4f54f44
    [responseEnvelope.build] => 1437064
    [estimatedAmountTable.currencyConversionList(0).baseAmount.code] => USD
    [estimatedAmountTable.currencyConversionList(0).baseAmount.amount] => 1.00
    [estimatedAmountTable.currencyConversionList(0).currencyList.currency(0).code] => EUR
    [estimatedAmountTable.currencyConversionList(0).currencyList.currency(0).amount] => 0.71
    [estimatedAmountTable.currencyConversionList(0).currencyList.currency(1).code] => USD
    [estimatedAmountTable.currencyConversionList(0).currencyList.currency(1).amount] => 1.00
    [estimatedAmountTable.currencyConversionList(0).currencyList.currency(2).code] => GBP
    [estimatedAmountTable.currencyConversionList(0).currencyList.currency(2).amount] => 0.48
)

执行此操作的函数是：

function _deformat($nvpstr) {
    foreach (explode('&', $nvpstr) as $nvp) {
        list($key, $value) = explode('=', $nvp);
        $data[$key] = $value;
    }
    return $data;
}

我想要这样的数组：

..
[EUR]
   [amount] => 0.71
[GBP]
   [amount] => 0.48
...

我可以获得密钥：

$new_key = substr(strrchr($key, "."), 1);

但在那之后我就陷入了困境。

你可以在数组上运行，
并更改键和值，例如：

foreach ($myarray as $key=>$val) {

    if(strstr($key,'code')){
      $myarray[$val] = $myarray[str_replace('code','amount',$key)];
      unset($myarray[$key]);
      unset($myarray[str_replace('code','amount',$key)]);
    }
}
