Description:
------------
We're calling our internal company service using Soap client. There is WSDL including XSD file and PHP client is able to call method properly and is also getting back proper response and headers, but there is NULL as a result, always, and after couple of hours we still do not have any clue why... Tested on different version of PHP 5.1 - 5.5 alpha, always the same results. Java/Ruby clients behave correctly.

I'm including test script below, which is however depending on WSDL + XSD files and response from internal server.

However, we captured real response and are putting those WSDL publicly with faked real response file, for you to easily try it for yourselves.

http://svg.kvalitne.cz/mix/soap/gis.wsdl
http://svg.kvalitne.cz/mix/soap/gis.xsd
http://svg.kvalitne.cz/mix/soap/response.xml (recorded and stubbed in-place response from real server)


Test script:
---------------
<?php
$wsdl = "http://svg.kvalitne.cz/mix/soap/gis.wsdl";
$client = new SoapClient($wsdl, array('trace' => 1, 'exceptions' => true, 'cache_wsdl' => WSDL_CACHE_NONE));
$params =  array('acContext' => array('countryIds' => 56, 'language' => 19),
                 'searchString' => "Josefská 505/10, Brno, Brno-město");
try {
   var_dump($client->__soapCall('getAddressOptions', array('parameters' => $params)));
} catch (Exception $e) {
   var_dump($e);
}
echo "\nLast Request: " . $client->__getLastRequest()."\n";
echo "Last Request Headers: " . $client->__getLastRequestHeaders()."\n\n";
echo "Last Response: " . $client->__getLastResponse()."\n";
echo "Last Response Headers: " . $client->__getLastResponseHeaders()."\n";


Expected result:
----------------
have $result, object with parsed response from server

Actual result:
--------------
we are getting NULL but do not know why
