how to call a soap webservice with struct input parameters? - php

Question

I want to interact with SOAP (as a client) and am not able to get the right syntax for input parameters. I have a WSDL URL that I have tested it with SoapUI and it returns result properly. There are two functions defined in the WSDL, but I only need one ("FirstFunction" below). Here is the script I run to get information on the available functions and types:
$client = new SoapClient("http://example.com/webservices?wsdl");
var_dump($client->__getFunctions());
var_dump($client->__getTypes());
And here is the output it generates:
array(
[0] => "FirstFunction Function1(FirstFunction $parameters)",
[1] => "SecondFunction Function2(SecondFunction $parameters)",
);
struct Amount {
anyURI Identifier;
Information charge;
string referenceCode;
}
struct Information {
string description;
decimal amount;
string code;
}
According to above result I developed my client with nusoap and php as below:
class Information
{
public $description;
public $amount;
public $code;
}
class Amount {
public $Identifier;
public $charge;
public $referenceCode;
}
$charge = new Information();
$charge->description = "ROUTE=XXX|abc=".$code;
$charge->amount = "NULL";
$charge->code = $chargecode;
$params = new Amount();
$params->Identifier =$num;
$params->charge = $charge;
$params->referenceCode = $refcode;
$header = new SoapHeader('key', $key);
$client->__setSoapHeaders($header);
try
{
$res = $client->__call('charge',array('parametrs'=>$params));
print_r($res->return);
}
catch(PDOException $e)
{
print_r($e->getMessage());
}
I get the following error as result:
Uncaught SoapFault exception: [soapenv:Server] unknown

In my opinion the best way to achieve it is to use a WSDL to php generator such as the PackageGenerator project. It abstracts the whole process so you only deal with objects without really worrying about SOAP.
