例子 1. Some examples

<?php
function Add($x,$y) {
  return $x+$y;
}

class LocalSoapClient extends SoapClient {

  function __construct($wsdl, $options) {
    parent::__construct($wsdl, $options);
    $this->server = new SoapServer($wsdl, $options);
    $this->server->addFunction('Add');
  }

  function __doRequest($request, $location, $action, $version) {
    ob_start();
    $this->server->handle($request);
    $response = ob_get_contents();
    ob_end_clean();
    return $response;
  }

}

$x = new LocalSoapClient(NULL,array('location'=>'test://',

Do you have problems with the PHP5 SoapClient when you need to send a request to a service with a ComplexType parameter?
 
Maybe because my service is build in Delphi with REMObjects SDK 3.0 I had the problems, maybe not. Anyway, this was my remedy:
<?php
$versie = new stdClass();//define a basic class object
$versie->versieID = $aVersie->versieID();//fill it with the exact attributes as your complextype Object in the wsdl is
$versie->versieNummer = $aVersie->versieNummer();
$versie->isActief = $aVersie->isActief();     
    
$soapVersieType = new SoapVar($versie , SOAP_ENC_OBJECT, "Versie", "http://127.0.0.1:8999/SOAP?wsdl"); //create the complex soap type, Versie is the name of my complex type in the wsdl, the latter url beeing the location of my wsdl.
 
try{
  $result =  $soapClient->BewaarVersie($this->sessieId,$soapVersieType); //BewaarVersie is a function derived from my WSDL with two params.
}
catch(SoapFault $e){
  trigger_error('Something soapy went wrong: '.$e->faultstring,E_USER_WARNING);            }
?>
After some more testing i found out that the conversion to the StdClass() object was not required. My 'Versie' local object has the attributes for the 'Versie' wsdl complex type defined as private vars and give no pain when i create the SoapVar with an instance of the local 'Versie' Object.

You can use this method to correct the SOAP request before sending it, if necessary. You can use the DOM API to accomplish that.

<?php

public ExtendedClient extends SoapClient {

   function __construct($wsdl, $options = null) {
     parent::__construct($wsdl, $options);
   }

   function __doRequest($request, $location, $action, $version) {
     $dom = new DOMDocument('1.0');

     try {

         //loads the SOAP request to the Document
         $dom->loadXML($request);

     } catch (DOMException $e) {
         die('Parse error with code ' . $e->code);
     }

     //create a XPath object to query the request
     $path = new DOMXPath($dom);

     //search for a node
     $nodesToFix = $path->query('//SOAP-ENV:Envelope/SOAP-ENV:Body/path/to/node');

     //check if nodes are ok
     $this->checkNodes($path, $nodesToFix);

     //save the modified SOAP request
     $request = $dom->saveXML();
    
     //doRequest
     return parent::__doRequest($request, $location, $action, $version);
   }

   function checkNodes(DOMXPath $path, DOMNodeList $nodes) {
     //iterate through the node list
     for ($i = 0; $ < $nodes->length; $i++) {
         $aNode = $nodes->item($i);

         //just an example
         if ($node->nodeValue == null) {
           //do something. For instance, let's remove it.
           $node->parentNode->removeChild($node);
         }
     }
   }
}
?>

This gives the developer the chance to solve interoperability problems with a web service.
