IP to country script.

[Monk3h]

This script should detect what contry a visitor is from via there IP and display there contrys flag.

 

However it does not work, please could you take a look and let me know if there are any obviouse errors as im stumped.

 

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

Print "$IPaddress"

include("IP_FILES/countries.php");
$three_letter_country_code=$countries[ $two_letter_country_code][0];
$country_name=$countries[$two_letter_country_code][1];

print "Two letters code: $two_letter_country_code<br>";
print "Three letters code: $three_letter_country_code<br>";
print "Country name: $country_name<br>";

// To display flag
$file_to_check="flags/$two_letter_country_code.gif";
if (file_exists($file_to_check)){
                print "<img src=flags/$file_to_check width=30 height=15><br>";
                }else{
                print "<img src=flags/noflag.gif width=30 height=15><br>";
                }

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;
}
?> 

 

 

Thanks in Advance,

Well, first of all, you are referring to the same directory (presumably) with two different casings (ip_files and IP_FILES). If the script is running on a non-Windows server, paths are case sensitive.

[Monk3h]

Nope, that was not it.

 

I'm reletivly new to functions.

 

Whats the most correct way to test the function?

[Kieran Menor]

I don't quite understand the logic of the function. Could you explain how it's supposed to work? Also, what do the files in ip_files contain? What do they look like?

[Monk3h]

an example of a file contained within ip_files is:

 

<?php
//4127195136-4143972351
$ranges=Array(
"4127195136" => array("4143972351","ZZ"),
);
?>

 

This is file 246.php

 

These files are used as referances to define which ips match which countrys.

[Kieran Menor]

Try using explode('.', $ip) instead of preg_split().

 

The best way to test the function itself would be to copy it to a seperate file and simply feed it an IP to see what it returns.
