SOAP request in PHP with CURL

Question 1

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.

Question 2

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. 
 ?>

Question 3

Have you tried SoapClient which is already built into PHP?

There is one tutorial: PHP - Soap Client calling .NET Web service

Here is another one, even though it was created for zend developers it should work fine.

Question 4

You can load the XML string into a SimpleXMLElement with simplexml_load_string and then find the attributes using XPath. It's important to register the namespaces involved with registerXPathNamespace before using XPath.

$xml = file_get_contents('example.xml'); // $xml should be the XML source string
$doc = simplexml_load_string($xml);
$doc->registerXPathNamespace('m', 'http://www.w3.org/2005/10/markup-validator');
$nodes = $doc->xpath('//m:markupvalidationresponse/m:validity');
$validity = strval($nodes[0]);
echo 'is valid: ', $validity, "n";
$nodes = $doc->xpath('//m:markupvalidationresponse/m:errors/m:errorcount');
$errorcount = strval($nodes[0]);
echo 'total errors: ', $errorcount, "n";
$nodes = $doc->xpath('//m:markupvalidationresponse/m:errors/m:errorlist/m:error');
foreach ($nodes as $node) {
    $nodes = $node->xpath('m:line'); 
    $line = strval($nodes[0]);
    $nodes = $node->xpath('m:col');
    $col = strval($nodes[0]);
    $nodes = $node->xpath('m:message');
    $message = strval($nodes[0]);
    echo 'line: ', $line, ', column: ', $col, ' message: ', $message, "n";
}

Question 5

# GET query goes in the URL you're hitting
$ch = curl_init('http://example.com/script.php?query=parameter');
# POST fields go here.
curl_setopt($ch, CURLOPT_POSTFIELDS, array('post' => 'parameter', 'values' => 'go here'));

PHP itself wouldn't decide to ignore the GET parameters if a POST is performed. It'll populate $_GET regardless of what kind of http verb was used to load the page - if there's query parameters in the URL, they'll go into $_GET.

If you're not getting $_POST and $_GET with this, then something is causing a redirect or otherwise killing something. e.g. have you check $_SERVER['REQUEST_METHOD'] to see if your code is actually running as a POST? PHP won't populate $_POST if a post wasn't actually performed. You may have sent a post to the server, but that doesn't mean your code will actually be executed under a POST regime - e.g. a mod_rewrite redirect.

Since you have FOLLOW_REDIRECT turned on, you're simply ASSUMING you're actually getting a post when your code executes.

Question 6

If anyone should be interested, i have provided the correct answer:

$soapUrl = "http://privpakservices.schenker.nu/package/package_1.3/packageservices.asmx?op=SearchCollectionPoint";

$xml_post_string = '<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><SearchCollectionPoint xmlns="http://privpakservices.schenker.nu/"><customerID>XXX</customerID><key>XXXXXX-XXXXXX</key><serviceID></serviceID><paramID>0</paramID><address>RiksvŠgen 5</address><postcode>59018</postcode><city>Mantorp</city><maxhits>10</maxhits></SearchCollectionPoint></soap12:Body></soap12:Envelope>';

$headers = array(
"POST /package/package_1.3/packageservices.asmx HTTP/1.1",
"Host: privpakservices.schenker.nu",
"Content-Type: application/soap+xml; charset=utf-8",
"Content-Length: ".strlen($xml_post_string)
); 

$url = $soapUrl;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

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

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

$parser = simplexml_load_string($response2);
