WSO2 WSF PHP - WSClientProxy - > __调用没有返回大响应

I've been trying to consume a service using WSClient in WSDL mode, but the response is always a array with an empty string.

I'm using WSO2 WSF for PHP(WSO2 Web Services Framework for PHP) and my PHP version is 5.3.

I think the problem could be the size of the response(I know its big). There is a way to define maxReceivedMessageSize and maxStringContentLength?

What should I do? There is a "WSO2 WSF for PHP" alternative library?

Code:

function getCatalog($options, $input)
{   
        $client = new WSClient($options);

        // get proxy object reference form client
        $proxy = $client->getProxy();

        //return $proxy->BuscaCatalogo($input);
        var_dump($proxy->BuscaCatalogo($input));
}

Output:

array(1) {
  ["BuscaCatalogoResult"]=>  string(0) ""
}

-- SOLVED This topic is little old, but here is an alternative for WSO2, https://code.google.com/p/wse-php/source/browse/examples/soap-wsa-example.php?r=407b920367574e85f1302a76ec5a2991b746d79c.

OBS: I'm a PHP developer

WSO2 PHP project is deprecated. The project is no longer maintained.
