Вот решение, которое я использую на своем сайте [www.vladonai.com] [1], оно 100% бесплатно (используется ежедневно обновляется [www.zaigadgets.com/geoip][2 ] source), очень быстро (возможно, намного быстрее, чем мог бы MySQL), и не требует базы данных . База данных хранится в двоичном файле, поэтому все, что вам нужно, это любая версия PHP.
Функция преобразования IP в название страны выглядит следующим образом:
function GetCountryFromIP($ip = "")
{
if ($ip == "")
$ip = $_SERVER['REMOTE_ADDR'];
//the db obtained from ZaiGadgets.com and converted using convert_ip2country_db_from_csv_to_binary_file_format function
$db_file_path = ip2Country_binary_db_filename;
if (!file_exists($db_file_path))
return "";
$db_file_handle = fopen($db_file_path, "rb");
if (!$db_file_handle)
return "";
$one_record_size = 10; //bytes
$low = 0;
$high = (filesize($db_file_path) / $one_record_size) - 1;
$mid = 0;
$ipFrom = 0;
$ipTo = 0;
$ipArrParts = explode('.', $ip);
$ipLong = ($ipArrParts[0] * 0x1000000) + ($ipArrParts[1] * 0x10000) + ($ipArrParts[2] * 0x100) + ($ipArrParts[3]);
$country = ""; //result
while($low <= $high)
{
$mid = (int)(($low + $high) / 2);
$file_pos = $mid * $one_record_size;
fseek($db_file_handle, $file_pos, SEEK_SET);
$ipFrom = ipdbv2_read32($db_file_handle);
$ipTo = ipdbv2_read32($db_file_handle);
if ($ipFrom < 0)
$ipFrom += pow(2, 32);
if ($ipTo < 0)
$ipTo += pow(2, 32);
if (($ipLong >= $ipFrom) && ($ipLong < $ipTo))
{
//found IP range :)
//echo "Found!!!!!<br>";
$country = fread($db_file_handle, 2);
fclose($db_file_handle);
$country = GetCountryNameFromCountryCode($country);
return $country;
} else
{
if($ipLong <$ipFrom)
{
$high = $mid - 1;
} else
{
$low = $mid + 1;
}
}
}
fclose($db_file_handle);
return "";
}
function ipdbv2_read32($db_file_handle)
{
$data = fread($db_file_handle, 4);
$output = unpack('V', $data);
$val_32_bit = $output[1];
if ($val_32_bit < 0)
$val_32_bit += 4294967296; //correct signed/unsigned issue on 32-bit platforms
return $val_32_bit;
}
Перед использованием вышеуказанной функции вам необходимо скомпилировать файл базы данных, используя следующую функцию:
define( "ip2Country_binary_db_filename", "ip2country_zaigadgets.bin" );
function convert_ip2country_db_from_csv_to_binary_file_format($input_file_path = "")
{
//convert dataf from ZaiGadgets.com to binary db format
if ($input_file_path == "")
$input_file_path = "db.csv";
$output_file_path = ip2Country_binary_db_filename;
$input_file_content = file_get_contents($input_file_path); //read_text_file_content($input_file_path);
if ($input_file_content == "")
{
echo "Error: empty input db - " . $input_file_path . "<br>";
return; //nothing to do
}
unlink($output_file_path); //delete file content
$out_fileHandle = fopen($output_file_path, "cb");
if (!$out_fileHandle)
{
echo "ERROR: Cannot Create file! " . $output_file_path . "<br>";
return;
}
$records_count = 0;
$input_file_lines = explode("\n", $input_file_content); //split it to lines
echo "Text lines count: " . count($input_file_lines) . "<br>";
//for ($input_line_n = 0; $input_line_n < 10; $input_line_n ++)
for ($input_line_n = 0; $input_line_n < count($input_file_lines); $input_line_n ++)
{
$sub_line = $input_file_lines[$input_line_n];
if (strlen($sub_line) > 0 && is_numeric($sub_line[0]))
{
$sub_values = explode(",", $input_file_lines[$input_line_n]);
if (count($sub_values) == 4)
{
$start_ip_addr = $sub_values[0];
$end_ip_addr = $sub_values[1];
$country_code = $sub_values[2];
if (strlen($country_code) == 2)
{
fwrite($out_fileHandle, pack("V", (float)$start_ip_addr), 4);
fwrite($out_fileHandle, pack("V", (float)$end_ip_addr), 4);
fwrite($out_fileHandle, $country_code, strlen($country_code));
$records_count ++;
} else
{
echo "Invalid line " . $input_line_n . " [wrong country len]: " . $sub_line . "<br>";
}
} else
{
echo "Invalid line " . $input_line_n . ": " . $sub_line . "<br>";
}
} else
if ($sub_line != "" && $sub_line[0] != '#' && $sub_line != "startip,endip,countrycode,countryname")
{
echo "Invalid line " . $input_line_n . ": " . $sub_line . "<br>";
}
}
fclose($out_fileHandle);
echo "Data size verification result: " . ($records_count * 10 == filesize($output_file_path) ? "OK" : "Error") . "<br>";
echo "Exported records (blocks) count: " . $records_count . "<br>";
echo "Exporting complete.<br>";
}
Теперь, если вам это нравится, вы можете использовать функцию ниже для преобразования двухбуквенного кода страны в читаемое название страны:
