从PHP中获取类的价值

Question

我正试图从货运网络服务获取操作消息。

在我填充$ myArr数组的内部后，我正在向这样的Web服务发送请求;

    $result = $client->queryShipment($myArr);   // it asks to web server whether cargo exist or not
    echo "<pre>";
    var_dump($result);
    echo "</pre>";

然后PHP结果是;

object(stdClass)#2 (1) {
  ["ShippingDeliveryVO"]=>
  object(stdClass)#3 (5) {
    ["outFlag"]=>
    string(1) "0"
    ["outResult"]=>
    string(11) "Success"
    ["count"]=>
    int(1)
    ["senderCustId"]=>
    int(1012883)
    ["shippingDeliveryDetailVO"]=>
    object(stdClass)#4 (6) {
      ["cargoKey"]=>
      string(12) "645558612997"
      ["invoiceKey"]=>
      string(10) "41db64ff4f"
      ["jobId"]=>
      int(4006477)
      ["operationCode"]=>
      int(0)
      ["operationMessage"]=>
      string(25) "There is no  process with cargo."
      ["operationStatus"]=>
      string(3) "NOP"
    }
  }
}

我需要从$ result中获取只有operationMessage的值。我怎么能这样做？

Answer 1

它很简单..

echo $result->ShippingDeliveryVO->shippingDeliveryDetailVO->operationMessage;

Answer 2

尝试：

$operationMessage = $result->ShippingDeliveryV0->shippingDeliveryDetailV0->operationMessage;
