Question

我有以下代码...

 $mainResponse = array(
                 "result" => array(
                 ),
                 "ack" => "success"
            );

       foreach($resp->searchResult->item as $item) {
         $itemId = $item->itemId;

         $addThisItem = array("itemId" => $itemId);
         array_push($mainResponse['result'], $addThisItem);
     }
}

   echo json_encode($mainResponse);

输出：

{"result":[{"itemId":{"0":"183851233368"}}],"ack":"success"}

期望的输出：

{"result":[{"itemId":"183851233368"},...],"ack":"success"}

编辑：

以XML形式接收响应。我使用$resp = simplexml_load_file($apicall);

$resp->searchResult->item

这是项目列表。诸如... [{"itemId":"1"},{"itemId":"2"}...]之类的东西包含了我所需的一切。如果我打印$itemId，则会得到我的itemId。

$ resp ...

我在做什么错了？

Answer 1

使用var_dump()检查值将有助于解决此类问题。

问题在于$itemId是一个SimpleXmlElement，并且没有按照您期望的方式进行编码。要针对特定情况解决此问题（可能会随不同或更多可变数据而变化），则可以根据需要强制转换该值。

$itemId = strval($item->itemId);
