รบกวนสอบแหล่งให้ข้อมูล ip 2 country database หน่อยครับ

<?php
function getLocation($ip){
$ch = curl_init();
$data = array('query' => $ip);
curl_setopt($ch, CURLOPT_URL, 'http://www.iplocation.net/tools/ip-locator.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

$x = curl_exec($ch);
$replace = str_replace("src='/tools/ip2location/flags","@CUT@",$x);
$string = explode("@CUT@",$replace);
$getCity = explode("</td><td>",$string[1]);
return 'City :&nbsp;'.$getCity[2].'&nbsp;&nbsp;Country : '.$getCity[count($getCity)-1];
}

echo getLocation("182.52.138.165");
?>
