php问题从函数返回一个数组

我通过联邦快递报价系统的卷曲来提取信息。我得到了必要的信息。卷曲功能正常。结果是准确的。 但是，当我尝试将结果添加到数组时，它不会将它们从函数传递到页面。它就像结果不存储在函数中一样。 

foreach($result->SOAPENVBody->RateReply->RateReplyDetails as $value) {
    $number = ++$number;
    $key1 = $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType;
    $value1 = $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->RatedShipmentDetails[0]->ShipmentRateDetail->TotalNetCharge->Amount;


    $options[$key1] = $value1;
}

    return $options;

我知道函数会像我一样通过数组设置 

$key1 = '1';
$value1 = 'Hello';

它将该信息传递给该页面。

当我通过$ key1和$ value1（echo $key1 . $value1;）回显卷曲结果时，它也会在页面上显示正确的信息。它只是不会将它传递给阵列。

下面我将回显来自echo的结果以显示正在检索的信息

FIRST_OVERNIGHT: 194.35
PRIORITY_OVERNIGHT: 147.83
STANDARD_OVERNIGHT: 133.77
FEDEX_2_DAY_AM: 111.54
FEDEX_2_DAY: 99.78
FEDEX_EXPRESS_SAVER: 89.71
FEDEX_GROUND: 20.92

而且我想要有人想看看我如何调用函数......这里是来自调用函数的主页面。

include_once('inc/functions/fedex_rate.php');
          $fedex_options = array();
         $fedex_options = fedex_rate($totalweight);

          foreach ($fedex_options as $key => $value) {
              echo '<tr><td colspan="2"><div class="margin10">'. $key .'</div></td><td colspan="2"><div class="margin10">'. $value .'</div></td></tr>'; 
          }

我甚至尝试在主页面的foreach循环中使用$options;然而，这也没有用。我终于看到了一个例子，其中某人使用函数中的数组细节设置了一个新数组，这就是我停止的地方。

以下是联邦快递费率报价完整功能减去敏感信息

<?

function getProperty($var) {
if ($var == 'key') return 'xxxxxxxxx';
if ($var == 'password') return 'xxxxxxxxx';
if ($var == 'account') return 'xxxxxx';
if ($var == 'meter') return 'xxxxx';
}


function fedex_rate($totalweight) {
//your account details here
$key = getProperty('key');
$password = getProperty('password');;
$account_number = getProperty('account');
$meter_number = getProperty('meter');
$residential = '1'; // 1 = true, 0 = false
    if ($residential == 1) { $residential = 'true'; }
    if ($residential == 0) { $residential = 'false'; }
if($residential == 1) { $servicetype = 'GROUND_HOME_DELIVERY'; }
if ($residential == 0) { $servicetype = ''; }



$recipient_address = 'xxxxxxx';
$recipient_city = 'xxxxxx';
$recipient_state = 'xx';
$recipient_zip = 'xxxxx';
$recipient_county = 'xx';

我能够通过在数组中的$ result之前和之后添加一个空值来使它工作......但为什么会这样呢？为什么我不能将$ result标记的值单独传递给数组？

$key1 = ''. $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType .'';

    $value1 = ''. $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->RatedShipmentDetails[0]->ShipmentRateDetail->TotalNetCharge->Amount .'';

任何人都可以告诉我为什么我不能将$ result直接传递给数组而没有任何额外的空白标签？这最终成为了问题所在，因此找出答案的人会得到接受的答案。

解析XML后，每个元素都是SimpleXMLElement对象，对象不能设置为数组中的键。

当你连接空字符串时，它变成了字符串而不是Object。如您所知，当您尝试回显对象时，它会调用__toString方法（如果已定义）。

如果您想调试此问题，请尝试致电，

var_dump($result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType)

您也可以通过以下方式解决此问题：

$key1 = (string)$result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType;

OR 

$key1 = $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType->__toString();

问题是之前在fedex_rate（）中没有定义$ options。只需在foreach之前将其定义为空数组。

 $options = array();
 foreach($result->SOAPENVBody->RateReply->RateReplyDetails as $value) {
    ....

答案 2 :(得分：0)

我能够通过在数组中的$ result之前和之后添加一个空值来实现它... 但是为什么会出现这种情况？为什么我无法传递值$ result标记自己的数组？

$key1 = ''. $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->ServiceType .'';

    $value1 = ''. $result->SOAPENVBody->RateReply->RateReplyDetails[$number]->RatedShipmentDetails[0]->ShipmentRateDetail->TotalNetCharge->Amount .'';
