Country to IP problem.

Whenever I run this script I get wrong results for country.
all the database and files can be downloaded from [url]http://software77.net/cgi-bin/ip-country/geo-ip.pl[/url]
But the Perl script gives the correct result. All the files are listed there.

If i change the $addr to “213.6.49.205” it shows wrong results and to should show Norway.

[code=php]
<?php

// Get the surfer’s ip address
$addr = getenv(“REMOTE_ADDR”);
echo “Your IP, IPv4: ” . $addr . “<br />n”;

$ip = sprintf(“%010u”, ip2long($addr));
echo “Your IP, numerical: ” . $ip . “<br /><br />n”;

// Initiate the timer
$time_start = microtime_float();

// Open the csv file for reading
$handle = fopen(“IpToCountry.csv”, “r”);

// Load array with start ips
$row = 1;
while (($buffer = fgets($handle, 9096)) !== FALSE) {
$array[$row] = $buffer;
$row++;
}

// Time loading
$time_end = microtime_float();
$time = substr($time_end – $time_start, 0, 7);
echo “Array with ” . $row . ” start ips loaded in $time seconds<br /><br />n”;

// Locate the row with our ip using bisection
$row_lower = ‘0’;
$row_upper = $row;
while (($row_upper – $row_lower) > 1) {
$row_midpt = (int) (($row_upper + $row_lower) / 2);
$buffer = $array[$row_midpt];
$start_ip = sprintf(“%010u”, substr($buffer, 1, strpos($buffer, “,”) – 1));
if ($ip >= $start_ip) {
$row_lower = $row_midpt;
} else {
$row_upper = $row_midpt;
}
}

// Time locating
$time_end = microtime_float();
$time = substr($time_end – $time_start, 0, 7);
echo “Row with your ip (# ” . $row_lower . “) located after $time seconds<br /><br />n”;

// Read the row with our ip
$buffer = $array[$row_lower];
$buffer = str_replace(“””, “”, $buffer);
$ipdata = explode(“,”, $buffer);
echo “Data retrieved from the csv file:<br />n”;
echo “ipstart = ” . sprintf(“%010u”, $ipdata[0]) . “<br />n”;
echo “ipend = ” . sprintf(“%010u”, $ipdata[1]) . “<br />n”;
echo “registry = ” . $ipdata[2] . “<br />n”;
echo “assigned = ” . date(‘j.n.Y’, $ipdata[3]) . “<br />n”;
echo “iso2 = ” . $ipdata[4] . “<br />n”;
echo “iso3 = ” . $ipdata[5] . “<br />n”;
echo “country = ” . $ipdata[6] . “<br /><br />n”;

// Close the csv file
fclose($handle);

// Total execution time
$time_end = microtime_float();
$time = substr($time_end – $time_start, 0, 7);
echo “Executing the whole script took $time secondsn”;

function microtime_float()
{
list($usec, $sec) = explode(” “, microtime());
return ((float)$usec + (float)$sec);
}
