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 = Net_GeoIP::getInstance('/path/to/geoipdb.dat', Net_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> * * @category Net * @package Net_GeoIP * @author Jim Winstead <jimw@apache.org> (original Maxmind PHP API) * @author Hans Lellelid <hans@xmpl.org> * @license LGPL http://www.gnu.org/licenses/lgpl.txt * @link http://pear.php.net/package/Net_GeoIp */ class Net_GeoIP { /** * Exception error code used for invalid IP address. */ const ERR_INVALID_IP = 218624992;
