1. Let's assume that you want to determine a city by IP in your PHP script.
   In this example we will use the GeoIp library.
2. Download GeoIP PHP-module.
3. Download free cities and countriesdatabases
4. Include geoipcity.inc and geoipregionvars.php files from the GeoIP module to your script.
   for example:
   include("geoipcity.inc");
   include("geoipregionvars.php");
5. Include the script city DB to your script.
   for example:
   $gi = geoip_open("/home/data_old/GeoIP-132_20070101/GeoIPCity.dat" , GEOIP_MEMORY_CACHE);
6. Add the string
   $record = geoip_record_by_addr($gi,"your_IP");
   into your script.
   Object $record will now contain all the needed information.
   For IP 212.58.251.202 $record will be
   geoiprecord Object
   (
   [country_code] => GB

   [longitude] => -0.23339999999999

7. Finally close the GeoIP DB:
   
   geoip_close($gi);
