If your application interacts with SOAP services and you wish to cache the responses for consumption later, then overriding SoapClient::__doRequest is the way to go.
For instance, if you know that the information presented doesn't change that often and you don't want to do a superfluous HTTP request, you can grab a response from a local cache and let SoapClient do the transformation to PHP data types.
<?php
class YourNamespace_SoapClient_Local extends SoapClient {
protected $cacheDocument = "";
public function __construct($wsdl, $options) {
parent::__construct($wsdl, $options);
}
/**
* SetCacheDocument() sets the previously cached document contents
*/
public function SetCacheDocument($document) {
$this->cacheDocument = $document;
}
/**
* __doRequest() overrides the standard SoapClient to handle a local request
*/
public function __doRequest() {
return $this->cacheDocument;
}
}
//---- code snippet showing usage within a class
//$document is a cached SOAP response document from a previous request, saved with SoapClient::__getLastResponse() to some cache somewhere
//for the purpose of this example, it is assumed that $this->wsdl, $this->options, $this->method and $this->params are set.
public function SoapRequest($document) {
$method = $this->method;
if($document == "") {
//uncached
try {
//default options
$client = new SoapClient($this->wsdl, $this->options);
$result = $client->$method($this->params);
//send the response to the cache
$this->CacheResponse($client->__getLastResponse());
} catch(SoapFault $fault) {
//log something
return FALSE;
}
} else {
//cached document
try {
/**
* the WSDL needs to be set to allow the method to be called on the client object
* and to trigger SoapClient to decode the response to native data types
*/
$client = new YourNamespace_SoapClient_Local($this->wsdl, $this->options);
$client->SetCacheDocument($document);
$result = $client->$method($this->params);
} catch (SoapFault $fault) {
//log something
return FALSE;
}
}
return $result;
}
?>
I'll leave you to work out the caching, plenty of options there.. ;)

Beschreibung
SoapClient
string
__doRequest
( string $request
, string $location
, string $action
, int $version
[, int $one_way

Ausführen einer SOAP-Anfrage über HTTP.
Diese Methode kann in einer vererbten Klasse überschrieben werden, wenn andere Transportarten, erweiterte XML-Verarbeitung oder anderes benötigt wird.
Parameter-Liste
- request
-
Die XML SOAP-Anfrage.
- location
-
Die URL der Anfrage.
- action
-
Die SOAP-Aktion.
- version
-
Die SOAP-Version.
- one_way
-
Rückgabewerte
Die XML SOAP-Antwort.
ChangeLog
| Version | Beschreibung |
|---|---|
| 5.1.3 | Der Parameter one_way wurde hinzugefügt. |

If you want to communicate with a default configured ASP.NET server with SOAP 1.1 support, override your __doRequest with the following code. Adjust the namespace parameter, and all is good to go.
<?php
class MSSoapClient extends SoapClient {
function __doRequest($request, $location, $action, $version) {
$namespace = "http://tempuri.com";
$request = preg_replace('/<ns1:(\w+)/', '<$1 xmlns="'.$namespace.'"', $request, 1);
$request = preg_replace('/<ns1:(\w+)/', '<$1', $request);
$request = str_replace(array('/ns1:', 'xmlns:ns1="'.$namespace.'"'), array('/', ''), $request);
// parent call
return parent::__doRequest($request, $location, $action, $version);
}
}
$client = new MSSoapClient(...);
?>
Hope this will save people endless hours of fiddling...

Note that __getLastRequest() data are buffered _before_ the call to __doRequest(). Thus any modifications you make to the XML while in __doRequest() will not be visible in the output of __getLastRequest(). This is so in at least v5.2.0

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.
