Question

currently I have an Zend application on default location
www.example.com/{controller}/{action}

but when a user visit from a specific country, how to detect their ip address and redirect them to this countryCode based url
www.example.com/uk/{controller}/{action}?

To detect the country from which the user are visiting I have written a helper:

require_once '../library/Ipinfo/ip2locationlite.class.php';

class Application_View_Helper_GetLocation extends Zend_View_Helper_Abstract
{
    public function getLocation()
    {

        $ipLite = new ip2location_lite;
        $ipLite->setKey('APIKEY');

        //Get errors and locations
        $locations = $ipLite->getCity($_SERVER['REMOTE_ADDR']);
        $errors = $ipLite->getError();

        $country = strtolower($locations['countryName']);

        return "$country";
    }
}

The above code will return the country name. If a user is visiting from France how can I rewrite the url so that the url becomes example.com/france/{controller}/{action}?

Refactor your view helper into a Controller Plugin and redirect.

A controller plugin can execute early in the request dispatch loop, therefore you can intercept a request and redirect to another response before any controller is loaded and rendered. Example below (warning, may contain bugs!)

class App_Plugin_DetectCountry extends Zend_Controller_Plugin_Abstract {

    public function preDispatch(Zend_Controller_Request_Abstract $request) {
        $ipLite = new ip2location_lite;
        $ipLite->setKey('APIKEY');

        //Get errors and locations
        $locations = $ipLite->getCity($_SERVER['REMOTE_ADDR']);
        $errors = $ipLite->getError();

        $country = strtolower($locations['countryName']);

        //Check if set country equals detected country
        if (!isset($_COOKIE['country']) || $country !== $_COOKIE['country']) {
            $_COOKIE['country'] = $country;
            $redirector = Zend_Controller_Action_HelperBroker::getStaticHelper('redirector');
            $redirector->gotoUrl($country . '/' . $request->getControllerName() . '/' . $request->getActionName()); 
        }
    }
}
