使用php调用Java Web服务时无法获得输出

Question

我已经使用Java创建了一个Web服务。 我使用以下代码使用php调用了Web服务。

$client = new SoapClient("http://localhost:8080/imageCom/wsdl/CompareImage.wsdl");
$stock = "http://localhost/pic/blueTshirts/b10.jpg";
$parameters= array("url"=>$stock);
$values = $client->checkSimilarity($parameters);       
var_dump($values);

当我运行代码时，得到以下输出。 但它不会显示结果

输出：object（stdClass）＃2（0）{}

这是我的WSDL

我做错了什么？ 请帮我。

问题是您将获得标准的类对象数组作为回报。

您必须相应地提取值

print_r（$ array）将递归打印数组。

您还可以遍历如下所示的对象数组，

foreach ($array as $key => $object) {
echo $object->object_property;
}

将数组视为事物的集合。 这是一个袋子，您可以在其中存储您的东西并为他们提供唯一的ID（密钥）并访问它们。
