The system used for country identification will work very fast in most cases.

Lets consider an ip like this: AAA.BBB.CCC.DDD (AAA is a number, etc).

When IP addresses starting with AAA may belong to many different contries (file AAA.php is big), finding corresponding country will require more time. Fortunately, in most cases, the file searched is very small (212 files from 255 are <5.000 bites). In those cases, this system will be faster than usage of a database.

Try this way:

<?
$IPaddress=$_SERVER['REMOTE_ADDR'];
$two_letter_country_code=iptocountry($IPaddress);

if ($two_letter_country_code=="UK"){
     include("This_file_for_UK.html");
      die();
    }else{
     include("This_file_for_others.html");
      die();
    }

function iptocountry($ip) {
    $numbers = preg_split( "/\./", $ip);
    include("ip_files/".$numbers[0].".php");
    $code=($numbers[0] * 16777216) ($numbers[1] * 65536) ($numbers[2] * 256) ($numbers[3]);
    foreach($ranges as $key => $value){
        if($key<=$code){
            if($ranges[$key][0]>=$code){$two_letter_country_code=$ranges[$key][1];break;}
            }
    }
    if ($two_letter_country_code==""){$two_letter_country_code="unkown";}
    return $two_letter_country_code;
}
?>

Try this two lines:

include("ip_files/countries.php");
print $countries[$country];
