SOAP request in PHP with CURL

[jaybo]

I am sending a SOAP request and the response is 200 ok but I am struggling to output the $response.

This is the website for the request Calculator Web Service and also the xml file document tree http://dneonline.com/calculator.asmx?wsdl

Here is my php code;

 

<?php
$xml = '<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <Add xmlns="http://tempuri.org/">
      <intA>1</intA>
      <intB>2</intB>
    </Add>
  </soap:Body>
</soap:Envelope>';

$url = "http://dneonline.com/calculator.asmx?wsdl";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

$headers = array();
array_push($headers, "Content-Type: text/xml; charset=utf-8");
array_push($headers, "Accept: text/xml");
array_push($headers, "Cache-Control: no-cache");
array_push($headers, "Pragma: no-cache");
array_push($headers, "SOAPAction: http://tempuri.org/Add");

if($xml != null) {
    curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml");
    array_push($headers, "Content-Length: " . strlen($xml));
}

// curl_setopt($ch, CURLOPT_USERPWD, "user_name:password"); /* If required */
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$response = curl_exec($ch);
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

echo "<pre>";
print_r($response->AddResponse);
echo "</pre>";
?>

Three problems.

First is finding out exactly what $response contains. Try to print_r or var_dump it directly without any ->AddResponse or other changes. You'll discover that the response isn't what you think it is.
Second is that $response is a string, not an object.

Third, and arguably most important, is that you're implementing SOAP on your own instead of using PHP's existing SOAP functionality.

I am seeing that $response returns bool(false).

 

I have been trying to use SoapClient but continuously get the error:

Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'https...'

I have looked in the php.ini file to address any exceptions and don't appear to get any success if I make adjustments there. This is the first time I have used SOAP and while it appears straight forward to me, I have some stumbling blocks to try to work though. As I have some experience of using cURL I have taken this route due to the resistance I am experiencing with SoapClient.
