Country from IP

**kreoton** · 10-05-2006, 06:13 AM

The problem is that function gethostbyaddr() dosn't gives any results and my function is unuseful:

PHP Code:


			
if ($hostname = gethostbyaddr($_SERVER['REMOTE_ADDR'])){
    if (substr($hostname,-2)!="lt"){
        header("Location:/en/");
        die();
    } else {
        header("Location:/lt/");
        die();
    }
} else {
    header("Location:/lt/");
    die();
}

Any ideas?

i can find a logical error:
if ($hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']))

i think u need "=="

$hostname = gethostbyaddr($_SERVER['REMOTE_ADDR'])

= will make $hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']), like you say
== is for conditions!

you conditioned if gethostbyaddr($_SERVER['REMOTE_ADDR']) can give to $hostname the value.

really srry kreoton, i interprete ur code wrongly. thought u want to compare two values.
gethostbyadd() returns a string containing the unmodified_ip on failure.

oh yes...

so... there's no need for if...

problem: not any IP has a dns... so... is not well

i found many scripts with big text data, but i dont think it is nessary to use them just to see if visitor is from one country (in my case lithuania).

then find out the ip-database of LT and it's over. don't forget to update the database on monthly basis
