php soap server/client

[TheVillain9]

i'm working on a php soap server. i'm not entirely sure if my problem is with the server or just if i need to do something else on the client side.

basically i created a sample client at:
http://67.96.115.172/dev/client.php

the server is suppose to return back an array of an object called City, which has city code,name,country and country_code. on the client when i try to iterate through the array i am doing...

$client = new SoapClient("http://67.96.115.172/dev/soap/TeamAmerica.wsdl");
$cities = $client->getCitiesByCountry("US");
echo "<BR>".count($cities)." cities found";
 
if(is_array($cities)) {
    foreach($cities as $city) {
        echo "\n<BR>".$city->City->city_code."cn:".$city->city_name;
    }
}

but that prints nothing!

my server is:

ini = ini_set("soap.wsdl_cache_enabled","0");
 
class City {
    var $city_code;
    var $city_name;
    var $country_code;
    var $country_name;
    function City($citycode,$cityname,$countryname,$countrycode) {
        $this->city_code=$citycode;
        $this->city_name=$cityname;
        $this->country_name=$countryname;
        $this->country_code=$countrycode;
    }
}
 
 
class SoapService {
    function getCitiesByCountry($country_code)
    {
        $cities = array();
        $db = mysql_connect('', '', '');
        mysql_select_db('dev_db', $db);
        $sql = "SELECT * FROM tblCity WHERE country_code='".$country_code."'";
        $city = mysql_query("SELECT * FROM tblCity WHERE country_code='".$country_code."'", $db);
        while($row = mysql_fetch_object($city))
        {    $cities[] = new City($row->CityCode,$row->CityName,$row->country,$country_code);
        }
        mysql_close($db);
        return $cities;
    }
}
 
$classmap = array('City' => 'City');
$server = new SoapServer("http://67.96.115.172/dev/soap/TeamAmerica.wsdl",array('classmap'=> $classmap));
$server->setClass("SoapService");
$server->handle();

thanks for the help/suggestions or links you could provide.
