How to make a PHP SOAP call using the SoapClient class

Question

I'm used to writing PHP code, but do not often use Object-Oriented coding. I now need to interact with SOAP (as a client) and am not able to get the syntax right. I've got a WSDL file which allows me to properly set up a new connection using the SoapClient class. However, I'm unable to actually make the right call and get data returned. I need to send the following (simplified) data:

• Contact ID
• Contact Name
• General Description
• Amount

There are two functions defined in the WSDL document, 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)",
);

array(
  [0] => struct Contact {
    id id;
    name name;
  }
  [1] => string "string description"
  [2] => string "int amount"
}

Say I want to make a call to the FirstFunction with the data:

• Contact ID: 100
• Contact Name: John
• General Description: Barrel of Oil
• Amount: 500

What would be the right syntax? I've been trying all sorts of options but it appears the soap structure is quite flexible so there are very many ways of doing this. Couldn't figure it out from the manual either...

UPDATE 1: tried sample from MMK:

$client = new SoapClient("http://example.com/webservices?wsdl");

$params = array(
  "id" => 100,
  "name" => "John",
  "description" => "Barrel of Oil",
  "amount" => 500,
);
$response = $client->__soapCall("Function1", array($params));

But I get this response: Object has no 'Contact' property. As you can see in the output of getTypes(), there is a struct called Contact, so I guess I somehow need to make clear my parameters include the Contact data, but the question is: how?

UPDATE 2: I've also tried these structures, same error.

$params = array(
  array(
    "id" => 100,
    "name" => "John",
  ),
  "Barrel of Oil",
  500,
);

As well as:

$params = array(
  "Contact" => array(
    "id" => 100,
    "name" => "John",
  ),
  "description" => "Barrel of Oil",
  "amount" => 500,
);

Error in both cases: Object has no 'Contact' property`

This is what you need to do.

I tried to recreate the situation...

• For this example, I created a .NET sample WebService (WS) with a WebMethod called Function1 expecting the following params:

Function1(Contact Contact, string description, int amount)

• Where Contact is just a model that has getters and setters for id and name like in your case.

• You can download the .NET sample WS at:

The code.

This is what you need to do at PHP side:

(Tested and working)

<?php
// Create Contact class
class Contact {
    public function __construct($id, $name) 
    {
        $this->id = $id;
        $this->name = $name;
    }
}

// Initialize WS with the WSDL
$client = new SoapClient("http://localhost:10139/Service1.asmx?wsdl");

// Create Contact obj
$contact = new Contact(100, "John");

// Set request params
$params = array(
  "Contact" => $contact,
  "description" => "Barrel of Oil",
  "amount" => 500,
);

// Invoke WS method (Function1) with the request params 
$response = $client->__soapCall("Function1", array($params));

// Print WS response
var_dump($response);

?>

Testing the whole thing.

• If you do print_r($params) you will see the following output, as your WS would expect:

Array ( [Contact] => Contact Object ( [id] => 100 [name] => John ) [description] => Barrel of Oil [amount] => 500 )

• When I debugged the .NET sample WS I got the following:

(As you can see, Contact object is not null nor the other params. That means your request was successfully done from PHP side)

• The response from the .NET sample WS was the expected one and this is what I got at PHP side:

object(stdClass)[3] public 'Function1Result' => string 'Detailed information of your request! id: 100, name: John, description: Barrel of Oil, amount: 500' (length=98)
