带有NaN的PHP soap响应返回

很抱歉，如果标题有误导性，我有点傻，但你能给我一点提示吗

我正在尝试bmi web服务

$client = new nusoap_client("http://www.beetledev.com/webservices/bmiservice.asmx");

$error = $client->getError();
if ($error) {
    echo "<h2>Constructor error</h2><pre>" . $error . "</pre>";
}

$result = $client->call('getBmiValue',array('w' => 62, 'h' =>167),null, 'http://www.beetledev.com/getBmiValue');


if ($client->fault) {
    echo "<h2>Fault</h2><pre>";
    print_r($result);
    echo "</pre>";
}
else {
    $error = $client->getError();
    if ($error) {
        echo "<h2>Error</h2><pre>" . $error . "</pre>";
    }
    else {
        echo "<h2>BMI</h2><pre>";
        echo $result;

echo "<h2>Request</h2>";
echo "<pre>" . htmlspecialchars($client->request, ENT_QUOTES) . "</pre>";
echo "<h2>Response</h2>";
echo "<pre>" . htmlspecialchars($client->response, ENT_QUOTES) . "</pre>";

我不知道我哪里做错了，我希望得到一点提示

谢谢

我找到了解决问题的办法

首先

改为

第二

改为

第三

问题是因为有两个变量？（对术语不确定），所以它被保存在一个数组中

请不要介意变量名

完成后，我得到了我的体重指数结果

BMI

NaN
