如何从php调用soap web服务

Question

I am able to consume soap web service using wizdler in my chrome but need to how can I consume it in my php code. From Wizdler I can get the proper response, for example I am posting the information like this:

Question is how to call this service from php code, what I did/trying so far is:

<?php

$wsdl = "http://64.20.37.90/VTWebServiceTest/VisualService.svc?wsdl";

$client = new SoapClient($wsdl);

$request_param = array(

    "storeNumber" => "valid value",
    "enterpriseId" => "valid value",
    "credential" => "valid value"

);

try {

    $responce_param = $client->GetCategories($request_param);
    $result = $responce_param->GetCategoriesResult;
    print_r($result);
} catch (Exception $e) {

    echo "Exception Error!";
    echo $e->getMessage();

}

?>

But it always returns message "12|Invalid service credential."

Can anybody help me out?

Thanks in advance.

Answer 1

maybe try this ...

$responce_param = $client->GetCategories($request_param);
print_r($responce_param);

or even

$responce_param = $client->GetCategories($request_param);
$values = get_object_vars($responce_param);
$myresults = object_to_array($values);
print_r($myresults);
