Store and present session variable

I am storing the following session variables

public function ingresoAction() {

        $usuario = $this->request->getPost('usuario', array('striptags', 'trim'));
        $password = $this->request->getPost('password', array('striptags', 'trim'));
        $request = $this->request;
        if ($request->isPost()) {
            $usua = SeperPerson::findFirst("SEPER_USUARI='$usuario' AND SEPER_CLAVEX='$password'");
            if (!$usua) {
                echo "no encontrado";
            } else {
                    $this->session->set("userId", $usua->SEPER_USUARI);
                    $this->session->set("email", $usua->SEPER_EMAILX);
                    $this->session->set("codigo", $usua->SEPER_CODIGO);
                    $this->session->set("username",  $usua->SEPER_USUARI);
                    $this->session->set("registered", true);
                    $this->session->set("loggedIn", true);
                    $this->session->set("tipox",  $usua->SEPER_TIPOXX);
                    $this->flash->success('Welcome ' .  $usua->SEPER_NOMBRE);
                    if ($usua->SEPER_TIPOXX == 'U') {
                        return $this->response->redirect('carrito/carrito');
                    } ELSE {
                        return $this->response->redirect('index');
                    }

            }
        }
    }

pero al presentarlas de la siguiente manera solo me presenta el texto "1"

echo $this->session->has("userId")

But in presenting them as follows, I only present the text "1"

The data is retrieved but not saved in the session variable or stored badly. What could it be?
