ip -> country, city Opcje

[robert1974]

czesc,
Czy ktos moze polecic API lub kod jak zrobic mapowanie z IP na panstwo+miasto?

znalazlem cos takiego ale nie dziala:
Grab the users IP address.
$ip = $_SERVER['REMOTE_ADDR'];

Get the users City, State and Country.
$sturl = 'http://api.hostip.info/get_html.php?ip='.$ip;
$ch = curl_init($sturl);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch,CURLOPT_TIMEOUT,10);
$res = curl_exec($ch);
$resinfo = curl_getinfo($ch);
curl_close($ch);
preg_match('/City: ([a-zA-Z].+[a-zA-Z]+)/', $res, $r);
preg_match('/ (([A-Z][A-Z])/', $res, $s);
$city = $r[1];
$country = $s[1];

Dziala, wielkie dzieki:

$user_ip=$_SERVER['REMOTE_ADDR'];

$sturl = 'http://freegeoip.net/json/'.$user_ip;

$json = file_get_contents($sturl);
$json_a = json_decode($json,true);

//var_dump($json_a);

$country=$json_a["country_code"];
$city=$json_a["city"];

... + zapis do bazy

niestety czasem sie wywala z takim bledem:

Warning: file_get_contents(http://freegeoip.net/json/176.35.234.145) [function.file-get-contents]: failed to open stream: HTTP request failed!

co poczac?
