but i want some code like which do execute this js file country wise some thing like this

http://j.maxmind.com/app/geoip.js

var country= geoip_country_code();

You want to serve up a .js, generated by PHP, whose content is dependent on the country from which the request comes?

If so, you can use the GeoIP extension for PHP: http://www.maxmind.com/app/php

In addition to Jack's answer (+1), here's some code that should work if you use the GeoIP PHP module:

addScript("http://domain.com/javascriptgenerator.php");

Then in javascriptgenerator.php, you simply do:

<?php 
header("Content-type: application/javascript"); //Tell the browser we're sending JS

require_once "Net/GeoIP.php"; //Path to GeoIP PHP module

$geoip = Net_GeoIP::getInstance("/path/to/geoipdb.dat");

try {
   switch ($geoip->lookupCountryCode($_SERVER['REMOTE_ADDR'])) { 
        case "CA":
           //Generate JS for Canadian users
        break;
        case "FR":
           //Generate JS for French users
        break;
        //Any number of case statements goes here
        default:
           //Show default JS code 
    }
} catch (Exception $e) {
   //Handle exception
   //You probably want to show the default JS code if the geo-location is unsuccesful
}
?>
