SOAP PHP fault parsing WSDL

Making a query through SoapClient() I receive the following error message with PHP, the truth is that I had never worked with this type of application

<?php
    try{
        $opts = array(
            'http' => array (
                'user_agent' => 'PHPSoapClient' 
            )
        );

        $context = stream_context_create($opts);

        $soapClientOptions = array(
            'stream_context' => $context,
            'cache_wsdl' => WSDL_CACHE_NONE
        );

        $cliente = new SoapClient($rutWWSDL, $soapClientOptions);

        $parametros = array(
            'security' => $security,
            'txn' => 'MANCOMPRANOR',
            'message' => $message
        );

        $respuesta = $cliente->cardtransaction($parametros);
        echo '<pre>'; print_r($respuesta); echo '</pre>';

    }
    catch(Exception $e){
        echo 'Exception capturada: ', $e->getMessage(), "\n";
    }
?>

I guess the error may be in some parameter of the $opts options, but I'm not sure how to fix it
