Get country location of an IP with native PHP

Question

Read on before you say this is a duplicate, it's not. (as far as I could see)

I want to get the county code in php from the client.

Yes I know you can do this using external sites or with the likes of "geoip_record_by_name" but I don't want to be dependent on an external site, and I can't install "pear" for php as im using shard Dreamhost hosting.

I thought I could just do something like this:

$output = shell_exec('whois '.$ip.' -H | grep country | awk \'{print $2}\'');
echo "<pre>$output</pre>";

But dreamhost seems to have an old version of whois (4.7.5), so I get this error on allot of IPs:

Unknown AS number or IP network. Please upgrade this program.

So unless someone knows how to get a binary of a newer version of whois onto dreamhost im stuck.

Or is there another way I could get the country code from the client who is loading the page?

Answer 1

Whois is just a client for the whois service, so technically you are still relying on an outside site. For the queries that fail, you could try falling back to another site for the query, such as hostip.info, who happen to have a decent API and seem friendly:

http://api.hostip.info/country.php?ip=4.2.2.2

returns

US

Good luck,

MaxMind provide a free PHP GeoIP country lookup class (there is also a free country+city lookup one).

The bit you want is what is mentioned under "Pure PHP module". This doesn't require you to install anything, or be dependent on them, nor does it need any special PHP modules installed. Just save the GeoIP data file somewhere, then use their provided class to interact with it.
