在PHP中从类中获取值

我正在尝试从cargo webservice获取操作消息

在填充$myArr数组的内部之后，我向web服务发送一个请求，如下所示

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

我只需要从$result中获取operationMessage值。我该怎么做呢？

太简单了

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

太简单了

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

尝试json_解码（$result，true）；然后以数组格式获得响应。获取所需的值。

$result->ShippingDeliveryVO->shippingDeliveryDetailVO->operationMessage

您可以从arraytries调用json_decode（$result，true）；然后以数组格式获得响应。获取所需的值。

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