How to encode PHP object to nuSOAP response? - php

Question

I'm building a simple WebService. I have a User PHP class and a webmethod getUser to retrieve a user's information.
I've declared a complexType and everything seems to work perfectly.
$server->wsdl->addComplexType('User',
'complexType','struct', 'all', '',
array( 'id' => array('name' => 'id', 'type' => 'xsd:int'),
'username' => array('name' => 'username','type' => 'xsd:string'),
'password' => array('name' => 'password','type' => 'xsd:string'),
'email' => array('name' => 'email','type' => 'xsd:string'),
'authority' => array('name' => 'authority','type' => 'xsd:int'),
'isActive' => array('name' => 'isActive','type' => 'xsd:int'),
'area' => array('name' => 'area','type' => 'xsd:string')
)
);
$server->register('ws_getUser',
array('user_id' => 'xsd:integer'),
array('user' => 'tns:User'),
$namespace,
"$namespace#ws_getUser",
'rpc',
'encoded',
'Retorna un usuario'
);
function ws_getUser($user_id){
return new soapval('return', 'tns:User', getUser($user_id));
}
However, on the getUser function I'm retrieving the user info as an assoc. array, not the User Object itself.
What I would like to do on getUser is to return a User instance instead, and have nuSOAP serialize it for me. Is this possible?
Edit: I've tried returning a new User() for testing purposes, but the response is
<user xsi:type="tns:User"/>

Guess I've found out an answer that may apply to this case here: http://www.php.net/manual/en/class.soapserver.php
If you want to return a custom object
array from a nusoap webservice, you
have to cast the objects to arrays
like so:
<?php
$users = array();
while($res = $db_obj->fetch_row())
{
$user = new user();
$user->Id = $res['id'];
$user->Username = $res['username'];
$user->Email = $res['email'];
$users[] = (array) $user;
}
return ($users);
