I am learning to write Soap service for a function which returns an array.The code is pasted below.I am not able to get the
array from the function.
B.php

Code:

<?php
class B
{
function get()
{
$input=array('G','B','K');
return $input;
}
}

?>

server.php

Code:

<?php
require('B.php');
require('nusoap.php');

//Create the server instance
$server=new soap_server();

//intializing the WSDL support
$server->configureWSDL('Inputwsdl','urn:Inputwsdl');

//define class properties
$server->wsdl->addComplexType(
'Input ',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),

array(
array('ref'=>'SOAP-ENC:arrayType',
'wsdl:arrayType'=>'tns:input[]')

),
'tns:input'
);

//Register the method to expose
$server->register(
'B.get',
array(),
array('return'=>'tns:input')
);

//calling the method
B::get();

// Use the request to (try to) invoke the service
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>

client.php

Code:

<?php
require_once('nusoap.php');
include('B.php');

$client = new soapclient('http://localhost/server.php?wsdl');
}
//call for the method
$return = $client->call('B.get',array());
print_r($return);

?>

The soap client does not outputs the array.I am confused.Can anyone please tell what the problem is?i am not able to figure out.
Thanks

After reading the previous post in this forum and few other sites on Nusoap

I came to a conclusion that a possible mistake might be in defining the complextype.so I have made few improvements in
the code which I have pasted below.
B.php

Code:

<?php
class B
{
function get()
{
return array('inp'=>'G','oup'=>'B','res'=>'K');

}
}

?>

server.php

Code:

<?php
require('B.php');
require('nusoap.php');

//Create the server instance
$server=new soap_server();

//intializing the WSDL support
$server->configureWSDL('Inputwsdl','urn:Inputwsdl');

//define class properties
$server->wsdl->addComplexType(
'Ret',
'complexType',
'struct',
'all',
'',
array(
'inp'=>array('name'=>'inp',type=>'xsd:string'),
'oup'=>array('name'=>'oup',type=>'xsd:string'),
'res'=>array('name'=>'res',type=>'xsd:string')
)
);
$server->wsdl->addComplexType(
'ArrayofRet', //name of the array
'complexType', //type class
'array', //type of the structure
'', //compositor
'SOAP-ENC:Array', //Restriction Base
array(), //element parameter is blank
//the attr parameter is an array instead of struct
array(
array('ref'=>'SOAP-ENC:arrayType',
'wsdl:arrayType'=>'tns:Ret[]')

),
'tns:Ret'
);

//Register the method to expose
$server->register(
'B.get',
array(),
array('return'=>'tns:Ret')
);

//calling the method
B::get();

// Use the request to (try to) invoke the service
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
?>

The client code is same as the one posted in previous post above.But still i could not get the array or output.
Any kind of lead on how to solve the problem will be of great help.since i am working on project of creating webservices for a php application using Nusoap.Whatever code i have pasted is just a sample one..am yet to work on the main one,i am just stuck up with this..

Thanks
