问题
I have just come across this great API: http://ipinfodb.com/ip_location_api.php
However, I would like to also retrieve the continent. Is this even possible as I can not find it.
Maybe there is another API that is freely available that will offer city, country and continent? I have tried Googles AJAX API but they don't offer continent either.
Maybe I going to have to just convert what I already have into continents, how?!
I hope this isn't too subjective!
Thanks all
回答1:
Why don't you map each CountryCodeXXCountryCode to the respective continent? Shouldn't be too hard since there are only about 200 countries and 5 or 7 continents.
EDIT: I have no knowledge of such prepared database in PHP, but here is a json_encode'd array for all the countries with the country code as key and continent name as value:
$json = '{"AD":"Europe","AE":"Asia","AF":"Asia","AG":"North America","AI":"North America","AL":"Europe","AM":"Asia","AN":"North America","AO":"Africa","AQ":"Antarctica","AR":"South America","AS":"Australia","AT":"Europe","AU":"Australia","AW":"North America","AZ":"Asia","BA":"Europe","BB":"North America","BD":"Asia","BE":"Europe","BF":"Africa","BG":"Europe","BH":"Asia","BI":"Africa","BJ":"Africa","BM":"North America","BN":"Asia","BO":"South America","BR":"South America","BS":"North America","BT":"Asia","BW":"Africa","BY":"Europe","BZ":"North America","CA":"North America","CC":"Asia","CD":"Africa","CF":"Africa","CG":"Africa","CH":"Europe","CI":"Africa","CK":"Australia","CL":"South America","CM":"Africa","CN":"Asia","CO":"South America","CR":"North America","CU":"North America","CV":"Africa","CX":"Asia","CY":"Asia","CZ":"Europe","DE":"Europe","DJ":"Africa","DK":"Europe","DM":"North America","DO":"North America","DZ":"Africa","EC":"South America","EE":"Europe","EG":"Africa","EH":"Africa","ER":"Africa","ES":"Europe","ET":"Africa","FI":"Europe","FJ":"Australia","FK":"South America","FM":"Australia","FO":"Europe","FR":"Europe","GA":"Africa","GB":"Europe","GD":"North America","GE":"Asia","GF":"South America","GG":"Europe","GH":"Africa","GI":"Europe","GL":"North America","GM":"Africa","GN":"Africa","GP":"North America","GQ":"Africa","GR":"Europe","GS":"Antarctica","GT":"North America","GU":"Australia","GW":"Africa","GY":"South America","HK":"Asia","HN":"North America","HR":"Europe","HT":"North America","HU":"Europe","ID":"Asia","IE":"Europe","IL":"Asia","IM":"Europe","IN":"Asia","IO":"Asia","IQ":"Asia","IR":"Asia","IS":"Europe","IT":"Europe","JE":"Europe","JM":"North America","JO":"Asia","JP":"Asia","KE":"Africa","KG":"Asia","KH":"Asia","KI":"Australia","KM":"Africa","KN":"North America","KP":"Asia","KR":"Asia","KW":"Asia","KY":"North America","KZ":"Asia","LA":"Asia","LB":"Asia","LC":"North America","LI":"Europe","LK":"Asia","LR":"Africa","LS":"Africa","LT":"Europe","LU":"Europe","LV":"Europe","LY":"Africa","MA":"Africa","MC":"Europe","MD":"Europe","ME":"Europe","MG":"Africa","MH":"Australia","MK":"Europe","ML":"Africa","MM":"Asia","MN":"Asia","MO":"Asia","MP":"Australia","MQ":"North America","MR":"Africa","MS":"North America","MT":"Europe","MU":"Africa","MV":"Asia","MW":"Africa","MX":"North America","MY":"Asia","MZ":"Africa","NA":"Africa","NC":"Australia","NE":"Africa","NF":"Australia","NG":"Africa","NI":"North America","NL":"Europe","NO":"Europe","NP":"Asia","NR":"Australia","NU":"Australia","NZ":"Australia","OM":"Asia","PA":"North America","PE":"South America","PF":"Australia","PG":"Australia","PH":"Asia","PK":"Asia","PL":"Europe","PM":"North America","PN":"Australia","PR":"North America","PS":"Asia","PT":"Europe","PW":"Australia","PY":"South America","QA":"Asia","RE":"Africa","RO":"Europe","RS":"Europe","RU":"Europe","RW":"Africa","SA":"Asia","SB":"Australia","SC":"Africa","SD":"Africa","SE":"Europe","SG":"Asia","SH":"Africa","SI":"Europe","SJ":"Europe","SK":"Europe","SL":"Africa","SM":"Europe","SN":"Africa","SO":"Africa","SR":"South America","ST":"Africa","SV":"North America","SY":"Asia","SZ":"Africa","TC":"North America","TD":"Africa","TF":"Antarctica","TG":"Africa","TH":"Asia","TJ":"Asia","TK":"Australia","TM":"Asia","TN":"Africa","TO":"Australia","TR":"Asia","TT":"North America","TV":"Australia","TW":"Asia","TZ":"Africa","UA":"Europe","UG":"Africa","US":"North America","UY":"South America","UZ":"Asia","VC":"North America","VE":"South America","VG":"North America","VI":"North America","VN":"Asia","VU":"Australia","WF":"Australia","WS":"Australia","YE":"Asia","YT":"Africa","ZA":"Africa","ZM":"Africa","ZW":"Africa"}';
Just call it with:
echo '<pre>';
print_r(json_decode($json, true));
echo '</pre>';

There's only 200ish countries and only 6 continents, so I would question why you need a web service to determine that bit of info... unless you plan on getting a lot of users from countries so politically unstable they will change names or cease to exist before your app does. Just keep a static list.
Also, not all countries are on a continent. New Zealand for example, isn't part of Australia (according to Wikipedia at least).
If you can determine the user's country programmatically, you have enough information to look up their continent in a static list which you own. It would take you an hour to assemble that info yourself and put it in a database or XML file, and it will rarely change. You've already spent nearly that amount of time trying to find out how to determine the continent dynamically.
回答3:
Have a look MaxMind GeoLite Country and MaxMind GeoLite City.
If it's the continent you're mainly after (I don't know if GeoLite stores that) you could always map the country codes from the GeoLite database to the country codes of the world database which MySql uses as a sample database. That has the continent for each country stored.

Try http://www.geobytes.com/IpLocator.htm?GetLocation
I use their online interface all the time, never tried the API.
