using string functions

[Sudhakar]

i am using $ip= $_SERVER['REMOTE_ADDR'] to retrieve the ip address of
the client for example if the value returned from $ip is
50.160.190.150

i would like to find out which country the request has come from. i
believe by using the third set of numbers (in this case=190) from an
ip address we can find out the country name. i can declare a variable
with a list of country names and the range of values, what i need help
is to extract the 3rd set of numbers from $ip.

as ip address keep changing the 3rd set of numbers can be single,
double or 3 digit number how can we extract the number that is stored
in $ip after the second dot and before the third dot

please advice.

thanks.

have a look at this..

http://www.phpclasses.org/browse/package/1477.html

I see explode used to extract the "."

Hope this helps..

yes, i agree with sathyashrayan, explode is what you need

$ip = $_SERVER['REMOTE_ADDR'];
$array_ip = explode('.',$ip);
$third_octet = $ip[2]; //remember, array = zero based

To get the 3rd Octet, you may {explode} the string as the previous
posters have said...

But if you have to get the Country Information, you'll have to get if
from a database.. Entire DBs like IP2Location etc. can be purchased..
(commecial, very accurate results)

Also, Try HostIP to get country informtion. They have a good API..
[FREE]
First, get the IP using $ip= $_SERVER['REMOTE_ADDR'];
Get the country and city name with
http://api.hostip.info/get_html.php?ip=$_SERVER['REMOTE_ADDR']
Try an example http://api.hostip.info/get_html.php?ip=222.88.238.16 -
This will show and example of the output format. Get the text contents
using $data = @file_get_contents($_GET['url']); or something and
extract the info from there//

Try that .. Hope it helps...

Cheers !

This can't be done reliably, not even with GeoIP databases. An IP is not
bound to any particular country nor does it say anything about where the
user is actually. All you can get are informations about the company the
IP belongs to.

>i

Where did you get that from? It's totally wrong. There's absolutely no
country information contained in an IP address, it's just an unsigned
32bit number (in case of IPv4).

well, maybe you can't obtain one hundred percent reliable data about
the country, not even when you ask to the user, but with the ip you
can at least try to guess, better than nothing don't you think?

Sure, it's a guess. Not more. Question is still for what the OP wants to
use it.

Actually its probably a lot better than a guess, since you normally
apply to the organisation in the country in which you are operating, for
an IP address range.

been involved with them for years. Intenational ISPs generally STILL use
netblocks registered in the country they are currently operating in, (it
makes for economical routing if nothing else) and whilst its possible to
use proxy server in china to access the USA from Europe, it generally is
a bit of a waste of time unles you are deliberately trying to hide your
tracks.

It might be a good guess, but it's still just a guess.

Apart from the proxy issue its more than a good guess. You can
generally ID the ISP's physical point of presence given the IP address
of the source ..

If you trace mine..think its in the headers..it will tell you probably
somewhere in North London or Essex. Only 60 miles away from me.
