How to send "int" array

$params = array(
    'countryId' => 119,
    'towns' => array(24, 172),
);
...
$client->setHeaders( $header );
...
$response = $client->call("GetSomething", $params );
xmlprint($client->request);

part of the request:

...
<GetSomething xmlns="urn:SomeName:Contracts:Soap11Gate:v1">
    <countryId>119</countryId>
    <towns/>
</GetSomething>
...

I need to get something like that:

...
<GetSomething xmlns="urn:SomeName:Contracts:Soap11Gate:v1"> 
  <countryId>119</countryId> 
  <towns> 
    <int xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">24</int> 
    <int xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">172</int> 
  </towns> 
</GetSomething>
...

Finally, I did

1. patch PHP Warning, nusoap.php on line 4694
from
$this->schemas->imports = true;
to
$list2 = true;

2. hack  ArrayOfint, nusoap.php on line 6059

...
if (is_object($value)) {
    $value = get_object_vars($value);
}
if (is_array($value)) {
    //hack 
    if (isset($uqType) && $uqType=="ArrayOfint" && isset($value) && is_array($value) )
    {
        $xml = "<$elementName>";
        foreach ($value as $id => $val) {
            $xml .= "<int xmlns=\"".$ns."\">".$val."</int>";
        }
        $xml .= "</$elementName>";
        return $xml;
    }
    //hack end
    
    $elementAttrs = $this->serializeComplexTypeAttributes($typeDef, $value, $ns, $uqType);
