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 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，我得到以下输出。但它不显示结果

输出：object(stdClass)#2 (0) { }

这是我的 WSDL

我做错了什么？请帮我。

问题是你得到了标准的类对象数组作为回报。

您必须相应地提取值

print_r($array) 将递归打印你的数组。

你也可以像下面这样循环遍历一个对象数组，

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它们提供唯一的 ID（密钥）并访问它们。
