Answer 1

Simply we can use Hostip API

<?php $country_code = file_get_contents("http://api.hostip.info/country.php"); <br/>if($country_code == "US"){ echo "You Are USA"; } <br/>else{ echo "You Are Not USA";} ?>

All Country codes are here.. http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2

Answer 2

There are some free services out there that let you make country and ip-based geolocalization from the client-side.

I've used the wipmania free JSONP service, it's really simple to use:

<script type="text/javascript">
  // plain JavaScript example
  function jsonpCallback(data) { 
    alert('Latitude: ' + data.latitude + 
          '\nLongitude: ' + data.longitude + 
          '\nCountry: ' + data.address.country); 
  }
</script>
<script src="http://api.wipmania.com/jsonp?callback=jsonpCallback"
        type="text/javascript"></script>

Or if you use a framework that supports JSONP, like jQuery you can:

// jQuery example
$.getJSON('http://api.wipmania.com/jsonp?callback=?', function (data) { 
  alert('Latitude: ' + data.latitude + 
        '\nLongitude: ' + data.longitude + 
        '\nCountry: ' + data.address.country); 
});
