/**
* GeoIP class provides an API for performing geo-location lookups based on IP
* address.
*
* To use this class you must have a [binary version] GeoIP database. There is
* a free GeoIP country database which can be obtained from Maxmind:
* {@link http://www.maxmind.com/app/geoip_country}
*
*
* <b>SIMPLE USE</b>
*
*
* Create an instance:
*
* <code>
* $geoip = GeoIP::getInstance('/path/to/geoipdb.dat', GeoIP::SHARED_MEMORY);
* </code>
*
* Depending on which database you are using (free, or one of paid versions)
* you must use appropriate lookup method:
*
* <code>
* // for free country db:
* $country_name = $geoip->lookupCountryName($_SERVER['REMOTE_ADDR']);
* $country_code = $geoip->lookupCountryCode($_SERVER['REMOTE_ADDR']);
*
* // for [non-free] region db:
* list($ctry_code, $region) = $geoip->lookupRegion($_SERVER['REMOTE_ADDR']);
*
* // for [non-free] city db:
* $location = $geoip->lookupLocation($_SERVER['REMOTE_ADDR']);
* print "city: " . $location->city . ", " . $location->region;
* print "lat: " . $location->latitude . ", long: " . $location->longitude;
*
* // for organization or ISP db:
* $org_or_isp_name = $geoip->lookupOrg($_SERVER['REMOTE_ADDR']);
* </code>
*
*
* <b>MULTIPLE INSTANCES</b>
*
*
* You can have several instances of this class, one for each database file
* you are using. You should use the static getInstance() singleton method
* to save on overhead of setting up database segments. Note that only one
* instance is stored per filename, and any flags will be ignored if an
* instance already exists for the specifiedfilename.
*
* <b>Special note on using SHARED_MEMORY flag</b>
*
* If you are using SHARED_MEMORY (shmop) you can only use SHARED_MEMORY for
* one (1) instance (i.e. for one database). Any subsequent attempts to
* instantiate using SHARED_MEMORY will read the same shared memory block
* already initialized, and therefore will cause problems since the expected
* database format won't match the database in the shared memory block.
*
* Note that there is no easy way to flag "nice errors" to prevent attempts
* to create new instances using SHARED_MEMORY flag and it is also not posible
* (in a safe way) to allow new instances to overwrite the shared memory block.
*
* In short, is you are using multiple databses, use the SHARED_MEMORY flag
* with care.
*
*
* <b>LOOKUPS ON HOSTNAMES</b>
*
*
* Note that this PHP API does NOT support lookups on hostnames. This is so
* that the public API can be kept simple and so that the lookup functions
* don't need to try name lookups if IP lookup fails (which would be the only
* way to keep the API simple and support name-based lookups).
*
* If you do not know the IP address, you can convert an name to IP very
* simply using PHP native functions or other libraries:
*
* <code>
* $geoip->lookupCountryName(gethostbyname('www.sunset.se'));
* </code>
*
* Or, if you don't know whether an address is a name or ip address, use
* application-level logic:
*
* <code>
* if (ip2long($ip_or_name) === false) {
* $ip = gethostbyname($ip_or_name);
* } else {
* $ip = $ip_or_name;
* }
* $ctry = $geoip->lookupCountryName($ip);
* </code>
