NuSOAP returns empty array - php

Question

I have the problem, that the NuSOAP server returns an empty array. I read and tried a lot of topics/things already but the result is always the same. I guess its only a minor thing you guys can solve within a minute.
I want to put an array of strings containing client information into another array that holds all servers:
Array
(
[Client1] => Array ([HostName] => 'TestHostName', [IP] => '1.1.1.1'),
[Client2] => Array ([HostName] => 'TestHostName', [IP] => '2.2.2.2'),
[Client3] => Array ([HostName] => 'TestHostName', [IP] => '3.3.3.3')
)
The arrays will get filled from mysql data, but for testing purposes I created a static array with data. Here is what I have got so far:
<?php
require_once ('lib/nusoap.php');
require('mysql.php');
$ServerName = 'server';
$ServiceName = 'CentralConfigService';
$ServiceURL = 'http://' . $ServerName . '/' . $ServiceName;
$Server = new soap_server();
$Server -> configureWSDL($ServiceName, $ServerName . '/' . $ServiceName);
function GetClientInfo($ClientName)
{
$Clients = array();
$ClientInfo = array(
'HostName' => 'testiname',
'IP' => 'testip',
'Type' => 'testtype',
'Config' => 'testconfig',
'Routines' => 'testroutines',
'Files' => 'testfiles',
'Access' => 'testaccess');
$Clients[$ClientName] = $ClientInfo;
return $Clients;
}
$Server -> wsdl -> addComplexType(
'ClientInfo',
'complexType',
'struct',
'sequence',
'',
array(
'HostName' => array('name' => 'HostName', 'type' => 'xsd:string'),
'IP' => array('name' => 'IP', 'type' => 'xsd:string'),
'Type' => array('name' => 'Type', 'type' => 'xsd:string'),
'Config' => array('name' => 'Config', 'type' => 'xsd:string'),
'Routines' => array('name' => 'Routines', 'type' => 'xsd:string'),
'Files' => array('name' => 'Files', 'type' => 'xsd:string'),
'Access' => array('name' => 'Access', 'type' => 'xsd:string')
)
);
$Server -> wsdl -> addComplexType(
'Clients',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(
array('ref' => 'SOAP-ENC:arrayType', 'wsdl:arrayType' => 'tns:ClientInfo')
),
'tns:Clients'
);
$Server -> register(
'GetClientInfo',
array('HostName' => 'xsd:string'),
array('return' => 'tns:Clients'),
$ServiceURL,
$ServiceURL . '#GetClientInfo',
'rpc',
'encoded',
'Get config by type');
if ( !isset( $HTTP_RAW_POST_DATA ) ) $HTTP_RAW_POST_DATA = file_get_contents( 'php://input' );
#$Server -> service($HTTP_RAW_POST_DATA);
?>
when I call the function "GetClientInfo", I always get an empty array:
Array
(
[0] => Array
(
[0] => Array
(
)
[1] => Array
(
)
[2] => Array
(
)
[3] => Array
(
)
[4] => Array
(
)
[5] => Array
(
)
[6] => Array
(
)
)
)
The client calls the function:
<?php
require_once('lib/nusoap.php');
$wsdl = "http://server/server.php?wsdl";
$client = new nusoap_client($wsdl, 'wsdl');
$result = $client -> call('GetClientInfo', array('ClientName'=>'Client1'));
print_r($result);
?>
Sorry for the long post. I hope it contains all necessary information.
Thanks a lot in advance!
Cheers,

I found my mistake. The complexType that includes the struct has to look like that:
$Server -> wsdl -> addComplexType(
'Clients',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(
array('ref' => 'SOAP-ENC:arrayType', 'wsdl:arrayType' => 'tns:ClientInfo')
),
'tns:ClientInfo'
So 'tns:ClientInfo' instead of 'tns:Clients' in the last line.
Here is a fully functioning example:
server.php
<?php
// Includes
require_once ('lib/nusoap.php');
require('mysql.php');
require('cc_functions.php');
// General SOAP configuration
$ServerName = 'server';
$ServiceName = 'CentralConfigService';
$ServiceURL = 'http://' . $ServerName . '/' . $ServiceName;
$Server = new soap_server();
$Server -> configureWSDL($ServiceName, $ServerName . '/' . $ServiceName);
function GetClientInfo($ClientName)
{
$Clients = array();
$Clients1 = array(
'HostName' => 'testiname',
'IP' => 'testip',
'Type' => 'testtype',
'Config' => 'testconfig',
'Routines' => 'testroutines',
'Files' => 'testfiles',
'Access' => 'testaccess');
$Clients2 = array(
'HostName' => 'testiname2',
'IP' => 'testip2',
'Type' => 'testtype2',
'Config' => 'testconfig2',
'Routines' => 'testroutines2',
'Files' => 'testfiles2',
'Access' => 'testaccess2');
array_push($Clients, $Clients1);
array_push($Clients, $Clients2);
return $Clients;
}
$Server -> wsdl -> addComplexType(
'ClientInfo',
'complexType',
'struct',
'all',
'',
array(
'ID' => array('name' => 'ID', 'type' => 'xsd:integer'),
'HostName' => array('name' => 'HostName', 'type' => 'xsd:string'),
'IP' => array('name' => 'IP', 'type' => 'xsd:string'),
'Type' => array('name' => 'Type', 'type' => 'xsd:string'),
'Config' => array('name' => 'Config', 'type' => 'xsd:string'),
'Routines' => array('name' => 'Routines', 'type' => 'xsd:string'),
'Files' => array('name' => 'Files', 'type' => 'xsd:string'),
'Access' => array('name' => 'Access', 'type' => 'xsd:string')
)
);
$Server -> wsdl -> addComplexType(
'Clients',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(
array('ref' => 'SOAP-ENC:arrayType', 'wsdl:arrayType' => 'tns:ClientInfo[]')
),
'tns:ClientInfo'
);
$Server -> register(
'GetClientInfo',
array('ClientName' => 'xsd:string'),
array('return' => 'tns:Clients'),
$ServiceURL,
$ServiceURL . '#GetClientInfo',
'',
'rpc',
'Get config by type');
if (!isset($HTTP_RAW_POST_DATA)) $HTTP_RAW_POST_DATA = file_get_contents('php://input');
#$Server -> service($HTTP_RAW_POST_DATA);
?>
client.php
<?php
require_once('lib/nusoap.php');
$wsdl = "http://server/server.php?wsdl";
$client = new nusoap_client($wsdl, 'wsdl');
$result = $client -> call('GetClientInfo', array('ClientName'=>''));
print_r($result);
?>
