Wich is the best way to create a WebService(using php nusoap) that can receive a multidimensional array so the data can be process and return certain information, let me show you what i got so far and couldnt make it work yet hope you can show me the way

[PHP]

$server->wsdl->addComplexType('newgroup', 'complexType', 'struct', 'all', '',
array(
'id' => array('name' => 'id', 'type' => 'xsd:string'),
'code' => array('name' => 'code', 'type' => 'xsd:string'),
'msg' => array('name' => 'msg', 'type' => 'xsd:string'))
);


$server->wsdl->addComplexType('kids', 'complexType', 'struct', 'all', '',
array('name' => array('name' => 'name', 'type' => 'xsd:string'),
'lname' => array('name' => 'lname', 'type' => 'xsd:string'),
'ename' => array('name' => 'ename', 'type' => 'xsd:string')
'age' => array('name' => 'r_tua', 'type' => 'xsd:int'),
'type' => array('name' => 'type', 'type' => 'xsd:string'))
);

$server->wsdl->addComplexType('listkids',
'complexType',
'array',
'',
'',
array (array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:kids[]'))
);




$server->register('MakeGroup',
array('listkids' => 'tns:listkids' ),
array('return' => 'tns:newgroup'),
$miURL
);

[/PHP]

on the client side i try to consume the webservice this way

[PHP]
$listkids = array(1 => array('name' => 'juan',
'lname' => 'robles',
'ename' => 'rivera',
'age' => 18,
'type' => 'H'),
2 => array('name' => 'juan',
'lname' => 'robles',
'ename' => 'rivera',
'age' => 18,
'type' => 'H'));

$result = $nusoapcliente->call(
$metodoALlamar,
array('listkids' => $listkids),
"uri:$serverURL/$serverScript",
"uri:$serverURL/$serverScript/$metodoALlamar" );
[/PHP]
