I'm looking for help with a php soapclient call:

The call is to a remote panel and I want to pull off the log data. There are various services published via the WSDL and I am able to use several with no issues. Here's the list:

array(12) { 
[0]=> string(77) "GetGPTimerChannelsResponse GetGPTimerChannels(GetGPTimerChannels     $parameters)" 
[1]=> string(74) "GetGPTimerChannelResponse GetGPTimerChannel(GetGPTimerChannel $parameters)" 
[2]=> string(74) "SetGPTimerChannelResponse SetGPTimerChannel(SetGPTimerChannel $parameters)" 
[3]=> string(47) "GetSlaveResponse GetSlave(GetSlave $parameters)" 
[4]=> string(71) "GetLogDataInlineResponse GetLogDataInline(GetLogDataInline $parameters)" 
[5]=> string(71) "GetLogItemInlineResponse GetLogItemInline(GetLogItemInline $parameters)" 
[6]=> string(59) "GetAlarmListResponse GetAlarmList(GetAlarmList $parameters)" 
[7]=> string(50) "GetSyslogResponse GetSyslog(GetSyslog $parameters)" 
[8]=> string(47) "SetSlaveResponse SetSlave(SetSlave $parameters)" 
[9]=> string(53) "GetVersionResponse GetVersion(GetVersion $parameters)" 
[10]=> string(53) "GetTDBInfoResponse GetTDBInfo(GetTDBInfo $parameters)" 
[11]=> string(53) "GetLogItemResponse GetLogItem(GetLogItem $parameters)" } 

I am trying to use the GetLogDataInline service which requires four parameters - these I'm passing as an array and all seems OK when doing the connection (the request/response takes around 30 seconds to process).

When I look at a var_dump / print_r of the result, it returns NULL, whereas when I do a call to the __getLastResponse all of the data I need to populate my local database is there.

Below is the code for the soapclient call:

$client = new soapclient ("http://192.168.1.126/cgi-bin/cgi.cgi?WSDL", 
array("trace" => 1,
"exceptions" => true,
"cache_wsdl" => WSDL_CACHE_NONE,
"features" => SOAP_SINGLE_ELEMENT_ARRAYS
));
$params = array (
        "ResponseType" => "Xml",
        "Step" => 15,
        "Start" => "2012-06-14T12:00:00+01:00",
        "End" => "2012-06-14T23:59:45+01:00"
);  
$result = $client -> GetLogDataInline ($params);

An extract from the var_dump / __getLastResponse is:

1. var_dump($client)

   object(SoapClient)#1 (4) { ["trace"]=> int(1) ["_features"]=> int(1) ["_soap_version"]=> int(1) ["sdl"]=> resource(4) of type (Unknown) }

2. var_dump($result)

   NULL

3. __getLastResponse

If you've got this far, thanks for taking the time.

Any help would be much appreciated.
