Remove tag, in submitting data to Soap Server with PHP

Question

Actual result:



    
        
            
                Ok
                0
                2011-04-26T19:13:55.421875+05:00

Expected result without tag.

I am doing it first time, and actually I know almost nothing about Soap Server, could you tell me, how can I remove return tag ?

this is the code on server side:

class PerformTransactionArgumentsResponse {
    public $errorMsg = "Ok";
    public $status = "0";
    public $timeStamp = "2011-04-26T19:13:55.421875+05:00";
}


class MyAPI {
    function PerformTransactionArguments() {
        return new PerformTransactionArgumentsResponse;
    }
}

$options=array('uri'=>'localhost/');
$server = new SoapServer(NULL,$options);
$server->setClass('MyAPI');
$server->handle();

In order to do what you want you must make a WSDL document and pass it both to the server and the client. Let's start creating a WSDL document named wsdl-pruebas.wsdl with the following content:



    
        
            
                
                    
                        
                        
                        
                    
                
            
        
    

    
    
        
    

    
        
            
            
        
    

    
        
        
            
            
            
                
            
        
    

    
        Returns an error message.

The definition seems overwhelming, but it's quite simple once you analize it section by section, which we'll analize below. First we define the type for the response here:

As you can see it's identical to your class. We'll use it later. Next we define the request and response messages:

We're defining an empty request, but a response of the type of your class. Take note of the name attribute, which values return. This is what you currently see in the response of the server. Next we define the "interface" for the operations of your SOAP server:

input and output simply point to the messages described above. Next we define the "details" of the portType:

Here soap:binding tells us it's using SOAP 1.1.

Finally we expose the binding through the service section:


    Returns an error message.

The soap:address point to the URL of your soap server script (in this example, http://localhost/pruebas/soap-server.php).

After defining the WSDL document, we code the soap server script (in this example will be named soap-server.php):

class PerformTransactionArgumentsResponse {
    public $errorMsg = "Ok";
    public $status = "0";
    public $timeStamp = "2011-04-26T19:13:55.421875+05:00";
}


class MyAPI {
    function PerformTransactionArguments() {
        return new PerformTransactionArgumentsResponse;
    }
}

$options = [
    'soap_version' => SOAP_1_1,
    'cache_wsdl' => WSDL_CACHE_NONE
];

$server = new SoapServer('http://localhost/pruebas/soap-pruebas.wsdl', $options);
$server->setClass('MyAPI');
$server->handle();

This time we provide the URL of our WSDL document and modify the $options array.

To see all this in action we create a SOAP client script (in this example will be soap-client.php):

try {
    $options = [
        'soap_version' => SOAP_1_1,
        'trace'=>1
    ];

    $client = new SOAPClient('http://localhost/pruebas/soap-pruebas.wsdl', $options);

    $response = $client->PerformTransactionArguments();

    header('Content-type:text/xml');
    echo $client->__getLastResponse();
}
catch (SoapFault $e) {
    echo $e;
}

Again, we specify the URL of our WSDL document. Running the client script will give this:


    
        
            Ok
            0
            2011-04-26T19:13:55.421875+05:00

What differs from the generated response of your soap server script?

In the soap:binding definition, if we modify the value of the stylesttribute to from document to rpc:

We'll get this response:


    
        
            
                Ok
                0
                2011-04-26T19:13:55.421875+05:00

Which is the response you're getting currently.

EDIT: Lastly, if we change the soap:body line:

to this:

The response will be:


    
        
            Ok
            0
            2011-04-26T19:13:55.421875+05:00

NOTE: For this I'm assuming the scripts and the WDSL are located in http://localhost/pruebas/.
