CI 3 using native sessions instead of driver

Would this be the best way to use the native php sessions instead of using their drivers? Since their drivers are just wrappers around session functions; I figured this would be the easiest way to do it still preserving library interface

The reason behind this is I am having issues with locking with mysql database driver and redis driver. I want to use native php sessions and swap in a redis driver at the php level.

This seems to work well. Any thoughts?

 

PHP Code:

<?php
    class MY_Session extends CI_Session 
    {
        public function __construct(array $params = array())
        {
            $CI =& get_instance();
                    
            // No sessions under CLI
            if (is_cli())
            {
                log_message('debug', 'Session: Initialization under CLI aborted.');
                return;
            }
            elseif ((bool) ini_get('session.auto_start'))
            {
                log_message('error', 'Session: session.auto_start is enabled in php.ini. Aborting.');
                return;
            }
            
            // Configuration ...
            $this->_configure($params);
            $this->_config['_sid_regexp'] = $this->_sid_regexp;
    
            // Sanitize the cookie, because apparently PHP doesn't do that for userspace handlers
            if (isset($_COOKIE[$this->_config['cookie_name']])
                && (
                    ! is_string($_COOKIE[$this->_config['cookie_name']])
                    OR ! preg_match('#\A'.$this->_sid_regexp.'\z#', $_COOKIE[$this->_config['cookie_name']])
                )
            )
            {
                unset($_COOKIE[$this->_config['cookie_name']]);
            }
    
            session_start();
    
            // Is session ID auto-regeneration configured? (ignoring ajax requests)
            if ((empty($_SERVER['HTTP_X_REQUESTED_WITH']) OR strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) !== 'xmlhttprequest')
                && ($regenerate_time = config_item('sess_time_to_update')) > 0
            )
            {
                if ( ! isset($_SESSION['__ci_last_regenerate']))
                {
                    $_SESSION['__ci_last_regenerate'] = time();
                }
                elseif ($_SESSION['__ci_last_regenerate'] < (time() - $regenerate_time))
                {
                    $this->sess_regenerate((bool) config_item('sess_regenerate_destroy'));
                }
            }
            // Another work-around ... PHP doesn't seem to send the session cookie
            // unless it is being currently created or regenerated
            elseif (isset($_COOKIE[$this->_config['cookie_name']]) && $_COOKIE[$this->_config['cookie_name']] === session_id())
            {
                setcookie(
                    $this->_config['cookie_name'],
                    session_id(),
                    (empty($this->_config['cookie_lifetime']) ? 0 : time() + $this->_config['cookie_lifetime']),
                    $this->_config['cookie_path'],
                    $this->_config['cookie_domain'],
                    $this->_config['cookie_secure'],
                    TRUE
                );
            }
            $this->_ci_init_vars();        
        }
    }
