Soap Client/Server "Invalid parameter (stdClass)"

Below I have included a stack trace of my PHP Client attempting to talk with the server. The client and server both read in the WSDL file file, so that part if of no concern.

As you can see by the second stack trace array item, I'm passing in a two dimensional array, but when the SoapServer does it's __doRequest() function, the array has been concatenated into a single, unmanageable string. Any solution on how to fix this would be greatly appreciated.

)

Here is the code I call the client with:

$test = $client->CreatePlan(array("session-id"=>"1", "plan"=>$pa)); //$pa variable shown in stack trace

and here is the relevant code on the server:

 public function _checkArguments($arguments, $validParameters) {
    $variables = "";
    foreach ($arguments as $arg) {
        $type = gettype($arg);
        echo "type is ".$type;
        if ($type == "object") {
            $type = get_class($arg);
        }
        $variables .= "(".$type.")";
    }
    if (!in_array($variables, $validParameters)) {
        throw new Exception("Invalid parameter types: ".str_replace(")(", ", ", $variables));
    }
    return true;
}

/**
 * Service Call: CreatePlan
 * Parameter options:
 * (CreatePlan) parameters
 * @param mixed,... See function description for parameter options
 * @return CreatePlanResponse
 * @throws Exception invalid function signature messages
 */
public function CreatePlan($mixed = null) {
    $validParameters = array(
        "(CreatePlan)",
    );
    $args = func_get_args();
    echo "<pre>Args are: ".print_r($args)."</pre>";

    $this->_checkArguments($args, $validParameters);
    return $this->__soapCall("CreatePlan", $args);
}

As you'd expect, the function fails on the func_get_args(). This has been driving me completely nuts for the past couple days, so any advice would be greatly appreciated.

EDIT: When I say it fails on the func_get_args I mean that I get a null variable return. So in the case of $args = func_get_args(), $args is null.

EDIT 2: In case it helps get my issue solved, here's the error from the Apache server's logs.

[error] [client 192.168.1.120] PHP Fatal error: Uncaught exception 'Exception' with message 'Invalid parameter types: (stdClass)' in /var/www/test_soap/Client_Billing.php:2200\nStack trace:\n#0 /var/www/test_soap/Client_Billing.php(2220): Client_Billing->_checkArguments(Array, Array)\n#1 [internal function]: Client_Billing->CreatePlan(Object(stdClass))\n#2 /var/www/test_soap/Client_Billing.php(2642): SoapServer->handle()\n#3 {main}\n thrown in /var/www/test_soap/Client_Billing.php on line 2200

The Code to run the soap server:

$server = new SoapServer("http://192.168.1.120/Client_Billing.wsdl");
$server->setClass("Client_Billing");
$server->handle();

So in case anyone's still following this thread. I found out what the issue was, and I wish I could say I'm not a complete idiot for not seeing it either, but I don't tend to make a habit of lying.

The whole issue stemmed from the fact that my "server" class, was extending my 'client' class, and recursively calling the __soapCall() from within the soap call itself.

For my experience, debugging webservices in PHP is a pain...But I will try to give you some help if I can.

What is that WSDLInterpreter you're using? Is that some third party class or some wrapper you developed just to do some extra things when you're creating the client? Is there any reason why you're not using SoapClient?

Have you tried replacing those arrays you're sending with actual instances of objects of the classes you are using and mentioning in the WSDL?

After many times I had issues with soap and PHP I use the following method to debug: first try to echo your responds:

echo htmlentities(var_dump($test,true));

If nothing there continue to this step: The best way to find soap errors is using sniffer and soapUI go in install soap UI, then create first project is very simple: http://www.soapui.org/Getting-Started/your-first-soapui-project.html

install packets sniffer

once you create your project and enter your WSDL you will be able call to the soap service methods , when you call these methods you will have to enter the parameters manually. enter them and run the function, if it runs OK, it means that somewhere on the PHP side there is some error, or its hidden in HTML comment. to understand better where is the error you will have to use the sniffer to catch the responds you got from the soap service, run the sniffer. Then you will have to analyze the output you get.

I think it caught for peculiarity support of dynamic objects in PHP SoapServer. If you can, try to replace array with described classes.

Are you using var_dump() and looking at the output in your browser? It could be that the browser is hiding the XML-tags that are actually there! Try "View Source" on the page.
