SOAP request in PHP with CURL

Question

Since the SOAP manual on php.net is not very noob friendly and I could not find any good examples I will post my question here.

How can I create PHP SOAP request to look like this?

POST /MySERVER/myWSDLservice.asmx HTTP/1.1
Host: connection.mywebsite.com
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://connection.mywebsite.com/MySERVER/GetCarType"

<?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>
  <GetCarType xmlns="http://connection.mywebsite.com/MySERVER/">
    <IDNumber>string</IDNumber>
  </GetCarType>
 </soap:Body>
</soap:Envelope>

Please note:

there is user/pass auth
SSL connection

Any suggestion / links / example much appreciated.

Tested and working!

with https, user & password

 <?php 
 //Data, connection, auth
 $dataFromTheForm = $_POST['fieldName']; // request data from the form
 $soapUrl = "https://connecting.website.com/soap.asmx?op=DoSomething"; // asmx URL of WSDL
 $soapUser = "username";  //  username
 $soapPassword = "password"; // password

 // xml post structure

 $xml_post_string = '<?xml version="1.0" encoding="utf-8"?>
                     <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
                       <soap:Body>
                         <GetItemPrice xmlns="http://connecting.website.com/WSDL_Service"> // xmlns value to be set to your WSDL URL
                           <PRICE>'.$dataFromTheForm.'</PRICE> 
                         </GetItemPrice >
                       </soap:Body>
                     </soap:Envelope>';   // data from the form, e.g. some ID number

    $headers = array(
                 "Content-type: text/xml;charset=\"utf-8\"",
                 "Accept: text/xml",
                 "Cache-Control: no-cache",
                 "Pragma: no-cache",
                 "SOAPAction: http://connecting.website.com/WSDL_Service/GetPrice", 
                 "Content-length: ".strlen($xml_post_string),
             ); //SOAPAction: your op URL

     $url = $soapUrl;

     // PHP cURL  for https connection with auth
     $ch = curl_init();
     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
     curl_setopt($ch, CURLOPT_URL, $url);
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
     curl_setopt($ch, CURLOPT_USERPWD, $soapUser.":".$soapPassword); // username and password - declared at the top of the doc
     curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
     curl_setopt($ch, CURLOPT_TIMEOUT, 10);
     curl_setopt($ch, CURLOPT_POST, true);
     curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP request
     curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

     // converting
     $response = curl_exec($ch); 
     curl_close($ch);

     // converting
     $response1 = str_replace("<soap:Body>","",$response);
     $response2 = str_replace("</soap:Body>","",$response1);

     // convertingc to XML
     $parser = simplexml_load_string($response2);
     // user $parser to get your data out of XML response and to display it. 
 ?>

The script works great and return XML SOAP response pastebin.com/9wzUV8Pw but I'm unable to parse the response into string, Any idea?

Without testing it the simplexml_load_string() cant handle the ":", right?

I'm trying to do consume a SOAP webservice using curl, but I only get an error that says "Unsupported Media Type". There is a way to force the Content-type header? When I set CURLOPT_POSTFIELDS the Content-type changes to "application/x-www-form-urlencoded".

Gustavo Straube Over a year ago

I found the problem here! I'm writing the headers using associative array. I only noted that when read this answer: stackoverflow.com/a/11091261/1128918

This, as of February 2017, still works as intended and helps people when they got headache while working with SOAP. I'd only like to point out the fact that, some servers, requires a prefix (like <clin:price>) for the xml tags (you can see that when the response contains a message about an unidentified sub-element)
