Question

After an upgrade of Codeigniter I get this message:

Cannot access protected property MY_Loader::$_ci_cached_vars

I know that this property is now protected so what can I do here?

extract($CI->load->_ci_cached_vars); // extract cached variables

I don’t know how to use the get_var method now, because the property is protected

this is get_var method

/**
     * Get Variable
     *
     * Check if a variable is set and retrieve it.
     *
     * @param   array
     * @return  void
     */
    public function get_var($key)
    {
        return isset($this->_ci_cached_vars[$key]) ? $this->_ci_cached_vars[$key] : NULL;
    }

How to refactor this?

Answer 1

   extract($CI->load->get_var($key));
