And i detect it's come from my Zend\XMLRpc\Client call

$httpClient = new \Zend\Http\Client();
$oxClient = new \Zend\XmlRpc\Client('http://xxx.com/www/api/v2/xmlrpc/',$httpClient);
$oxSession = $this->oxClient->call('ox.logon',$oxLogin); 
$zone_list = $this->oxClient->call('ox.agencyZoneStatistics',array($oxSession,$agency_id)); 

I call to OpenX API system. At the first call with logon was success but the second fail ??! I think my problem point in decodeChunkedBody function at Zend\Http\Response.php. It's cannt understand chunked response from OpenX

protected function decodeChunkedBody($body)
{
    $decBody = '';

    while (trim($body)) {
        if (! preg_match("/^([\da-fA-F]+)[^\r\n]*\r\n/sm", $body, $m)) {
            throw new Exception\RuntimeException(
                "Error parsing body - doesn't seem to be a chunked message"
            );
        }

        $length   = hexdec(trim($m[1]));
        $cut      = strlen($m[0]);
        $decBody .= substr($body, $cut, $length);
        $body     = substr($body, $cut + $length + 2);
    }

    return $decBody;
}

I stuck here. The first old lib (2.0.4) work well , i upgrade it because the requirement for using zfcuser,zfcbase. But the new lib (2.0.6) got this error in second call ( and any except logon method ).

A while back I had a problem using XML-RPC to access OpenX API but it turns out the solution was simple: http://www.openxrest.com/xml-rpc2-returns-empty-decoded-result/

Also, you should turn debug mode on. See this link to know how to turn it on: http://devzone.zend.com/97/xml_rpc-client/#Heading9
