Getting the XML as string for a SoapVar variable - without a webservice (locally)?

Question

Consider this simple snippet of code:

Answer 1

Ok, thanks to Inspect XML created by PHP SoapClient call before/without sending the request, I think I got it solved - one needs to create a separate debug SoapClient extended class, here is the modified OP code with it:

class SoapClientDebug extends SoapClient
{
  public function __doRequest($request, $location, $action, $version, $one_way = 0) {
    // Add code to inspect/dissect/debug/adjust the XML given in $request here
    //echo "$request\n"; // OK, but XML string in single line
    $doc = new DomDocument('1.0');
    $doc->preserveWhiteSpace = false;
    $doc->formatOutput = true;
    $doc->loadXML($request);
    $xml_string = $doc->saveXML();
    echo "$xml_string\n";
    // Uncomment the following line, if you actually want to do the request
    // return parent::__doRequest($request, $location, $action, $version, $one_way);
    return ""; # avoids the PHP Fatal error:  Uncaught SoapFault exception: [Client] SoapClient::__doRequest() returned non string value in .../__thisfile__.php:32

  }
}

# http://php.net/manual/en/soapvar.soapvar.php
$parm = array();
$parm[] = new SoapVar('123', XSD_STRING, null, null, 'customerNo' );
$parm[] = new SoapVar('THIS', XSD_STRING, null, null, 'selection' );
$parm[] = new SoapVar('THAT', XSD_STRING, null, null, 'selection' );
$out = new SoapVar($parm, SOAP_ENC_OBJECT);

var_dump($out);

//~ $dbgclient = new SoapClientDebug(NULL); # "URI of the WSDL file or NULL if working in non-WSDL mode." http://php.net/manual/en/soapclient.soapclient.php
$dbgclient = new SoapClientDebug(null, array('location' => "http://localhost/soap.php",
                                              'uri'      => "http://test-uri/"));
$dbgclient->testVar($out);

?>

This, at end, will print out:

  
    
      
        123
        THIS
        THAT
      
    
  

... which is what I wanted, I guess...
