Geo-IP Tracking

[Slap Dot]

How do you trace the country, state, and city from one IP using PHP? Or can I get an sample code from PHP or any other language?

The only way to match IP addresses to geo-location is to refer to a database that links the two. There's nothing encoded in an IP address that implies anything about geo-location.

There are companies that supply such databases. But to answer your question, you cannot use PHP alone to find this information. A variable like $_PHP_CITY would be awesome, but it just doesn't exist.

Yea, I know. I was hoping someone can hook me up with a DB export of the info and sample code of any language.

plug in maxmind's PHP API:

If you don't own your own server or your admin won't install the mod_geoip Apache module, then use the pure php module

Go to Jadebucks

They have a simple javascript for redirecting Netscape Chinese Browsers. You may be able to play with it so it does what you want.

You could take a look at the IP-to-Country http://www.ip-to-country.com/ database. You can download it for free. Don't know if it's free for commercial use, but at least you can test how it works.

Yes, very fast is http://www.ip-to-country.com/ base + own script 9string
sample :

$ip_addr=getenv("REMOTE_ADDR");
$ip_int = ip2long($ip_addr);
$query_country = "select * from ip_country
where '$ip_int'>=ip_low_long
and '$ip_int'<=ip_high_long";
$result_country = mysql_query($query_country);
$num_country = mysql_num_rows($result_country);
$row = mysql_fetch_array ($result_country);
$ip = htmlspecialchars(stripslashes($row["ip"]));
