PHP Wrapper for Funnelback Frontends

Managed by | Updated .

This code is an extremely simple PHP wrapper example. It demonstrates a minimal viable implementation to request Funnelback results from the server side in a PHP environment. It should not be considered viable for production.

Please note that this example does not include cookie support and - as such - will not be usable in conjunction with Funnelback search sessions.

                // Rebuild our query string - do not filter the CGI params

                // if none is given. 
                $url .= $default_cgi_string;
