How to show user country by IP (II post)

Hi all, I send this message for the second time becouse I had problems with the mailing list. I would like to show the country of the user provider (only by organizations databases). I haven't problem with provider located in europe, simply this code: $indirizzo_cliente = $_SERVER["REMOTE_ADDR"]; $fp = file ("http://www.ripe.net/whois?form_type=simple&full_query_string=&searchtext=$ indirizzo_cliente"); while (list ($line_num, $line) = each ($fp)) { if(strstr($line,"country")!=""){ // or other fields like person, address etc etc $lineaok[$i]=$line; } } THE PROBLEM cames when a want to show the country of providers located in NORTH AMERICA, in this case I have to send the query by POST METHOD (ARIN DATABASE). So I can't match both the results of the two interrogation in the same php page, get and post method in the same php script. Please don't suggest method based on commercial services, a would like to find a programming based solution. Sebastiano
