I am using the binary version of MaxMind’s GEOIPCITY database. The following code gives me all the information I need about my visitors:

include("geoipcity.inc");
include("geoipregionvars.php");

$gi = geoip_open("GeoLiteCity.dat", GEOIP_STANDARD);
print_r( geoip_db_get_all_info() );
$record = geoip_record_by_addr($gi, $user_ip);
print $record->country_code . " " . $record->country_code3 . " " . $record->country_name . "<br /><br />";
print $record->region . " " . $GEOIP_REGION_NAME[$record->country_code][$record->region] . "<br /><br />";
print $record->city . "<br /><br />";
print $record->postal_code . "<br /><br />";
print $record->latitude . "<br /><br />";
print $record->longitude . "<br /><br />";
print $record->metro_code . "<br /><br />";
print $record->area_code . "<br /><br />";
print $record->continent_code . "<br /><br />";
geoip_close($gi);

I don’t really need anything beyond this like network speed, ISP, etc.

My issue is, there are parts of my site where I need to display all the cities under a particular state, or all the states/regions in a particular country. For example I need to do this in the registration form.

Is there no way to get these lists by querying the binary file? or do I have to handle all that from the mysql version?

I would prefer to use only the binary version since it’s faster, but now I am not sure if the displaying of all zips under a certain city or all states under a certain country, etc. is possible without using the mysql version. Does one need to use both?

    The GeoIP database is intended for one purpose, and one purpose only: to return location information for an input IP. It is not a general-purpose GIS database, and will not work for that purpose, as there are some locations which won’t be returned for any IP. (For instance, a small town with no local Internet service might not appear in their database at all, since any IP in that town would likely be categorized under another nearby city.)

    Maxmind has a separate “World Cities with Population” database that is more likely to be suitable for this purpose: http://www.maxmind.com/app/worldcities
