Why can't get response from soap wsdl php Curl server?

Question

PHP

I myself am not friends with soap wsdl yet, although I have read a bunch of articles about them, but the basic basics do not fit in my head.
I found an example of accessing the server via Curl on the Internet and substituted my login, password and wsdl:

<?php
  
  $query = '<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<soap:Header/>
<soap:Body>
<m:Calc xmlns:m="http://www.cargo3.ru">

<m:password>2016</m:password>       //password

</m:Calc>

</soap:Envelope>';

  $ch = curl_init();
  curl_setopt_array(
    $ch,
    array(
      CURLOPT_URL => 'http://lk-test.cse.ru/1c/ws/web1c.1cws?wsdl',        //wsdl
      CURLOPT_VERBOSE => FALSE,
      CURLOPT_RETURNTRANSFER => TRUE,
      CURLOPT_POST => TRUE,
      CURLOPT_POSTFIELDS => $query,
      CURLOPT_HEADER => FALSE,
      CURLOPT_HTTPHEADER => array('Content-Type: text/xml')
    )
  );
  $response = curl_exec($ch);
  curl_close($ch);
  
  header('Content-Type: text/xml');
  print_r($response);
  
?>

The only response is this:
This XML file does not appear to have any style information associated with it. The document tree is shown below.
What am I doing wrong? Tell me please.

Why are you doing this manually?
Let's start with the fact that php has an extension php-soap , which only feeds the wsdl address and calls ready-made methods.
As a last resort, you can use the ready-made nusoap library
