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.

look for the free maxmind's geoip stuff:

WTF? Third byte of the IP address definitely does not correlate with the country. Use apache's mod_geoip.

The IP address block are managed by ARIN (do a google search..), the numeric value have no correlation with country. You need to use geoip. Check ARIN to learn more about the IP address blocks.
