PHP – Send a SOAP Request by cURL

We can use the PHP cURL library to generate simple HTTP POST request. The following example shows you how to create a simple SOAP request using cURL.

Create the soap-server.php which write the SOAP request into soap-request.xml in web folder.

<?php
  $HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
  $f = fopen("./soap-request.xml", "w");
  fwrite($f, $HTTP_RAW_POST_DATA);
  fclose($f);
?>

 

The next step is creating the soap-client.php which generate the SOAP request using the cURL library and send it to the soap-server.php URL.

<?php
  $soap_request  = "<?xml version=\"1.0\"?>\n";
  $soap_request .= "<soap:Envelope xmlns:soap=\"http://www.w3.org/2001/12/soap-envelope\" soap:encodingStyle=\"http://www.w3.org/2001/12/soap-encoding\">\n";
  $soap_request .= "  <soap:Body xmlns:m=\"http://www.example.org/stock\">\n";
  $soap_request .= "    <m:GetStockPrice>\n";
  $soap_request .= "      <m:StockName>IBM</m:StockName>\n";
  $soap_request .= "    </m:GetStockPrice>\n";
  $soap_request .= "  </soap:Body>\n";
  $soap_request .= "</soap:Envelope>";

  $header = array(
    "Content-type: text/xml;charset=\"utf-8\"",
    "Accept: text/xml",
    "Cache-Control: no-cache",
    "Pragma: no-cache",
    "SOAPAction: \"run\"",
    "Content-length: ".strlen($soap_request),
  );

  $soap_do = curl_init();
  curl_setopt($soap_do, CURLOPT_URL, "http://localhost/php-soap-curl/soap-server.php" );
  curl_setopt($soap_do, CURLOPT_CONNECTTIMEOUT, 10);
  curl_setopt($soap_do, CURLOPT_TIMEOUT,        10);
  curl_setopt($soap_do, CURLOPT_RETURNTRANSFER, true );
  curl_setopt($soap_do, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($soap_do, CURLOPT_SSL_VERIFYHOST, false);
  curl_setopt($soap_do, CURLOPT_POST,           true );
  curl_setopt($soap_do, CURLOPT_POSTFIELDS,     $soap_request);
  curl_setopt($soap_do, CURLOPT_HTTPHEADER,     $header);

  if(curl_exec($soap_do) === false) {
    $err = 'Curl error: ' . curl_error($soap_do);
    curl_close($soap_do);
    print $err;
  } else {
    curl_close($soap_do);
    print 'Operation completed without any errors';
  }
?>

 

Enter the soap-client.php URL in browser to send the SOAP message. If success, Operation completed without any errors will be shown and the soap-request.xml will be created.

<?xml version="1.0"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">
  <soap:Body xmlns:m="http://www.example.org/stock">
    <m:GetStockPrice>
      <m:StockName>IBM</m:StockName>
    </m:GetStockPrice>
  </soap:Body>
</soap:Envelope>

 

Done =)

  1. Thank you very much. I just had some trouble with native SoapClient objects and I decided to send a raw xml message. Your post has helped me a lot.

  2. Thanks very much for this post. It has been very informative!
    I tried this code to send a raw SOAP request using authentication but all I get back from the server is the full wsdl file for the service. Does this method handle authentication as well over https?

    Thanks again,

  4. I didn’t know SOAP but a job dropped on my lap that needed integration of a SOAP service without WDSL, which most other tutorials use, I was scratching my head as the service’s manual only provided the XML, no URI or WDSL link. Thanks for sharing your expertise, I totally know how to continue now, thanks!

      2. Hello ykyuen,
        First of all thanks for your reply long ago 🙂 .
        Because of other projects I had to put all of this on hold.
        At the moment I havent tried my own SOAP site yet, because I’m trying to get your instructions to work.

        Everything works from creating the soap-server.php and soap-client.php and when I run the client I get a “Operation completed without any errors” sign. However, when I look at the xml output it is blanc. Do you also have this problem?
