GeoIP没有显示所有信息

Question

所以我有这个错误，我下载了最新的  geoipcity.inc | geoipregionvars.inc | GeoLiteCity.dat

所以这是我的代码：

<?php
/**
 * Querying against GeoIP/Lite City
 * This will fetch country along with city information
 */

include("geoipcity.inc");
include("geoipregionvars.php");

$giCity = geoip_open("GeoLiteCity.dat",GEOIP_STANDARD);

$ip = "99.99.99.99";
$record = geoip_record_by_addr($giCity, $ip);

echo "Getting Country and City detail by IP Address <br /><br />";

echo "IP: " . $ip . "<br /><br />";

echo "Country Code: " . $record->country_code .  "<br />" .
     "Country Code3: " . $record->country_code . "<br />" .
     "Country Name: " . $record->country_name . "<br />" .
     "Region Code: " . $record->region . "<br />" .
     "City: " . $record->city . "<br />" .
     "Postal Code: " . $record->postal_code . "<br />" .
     "Latitude: " . $record->latitude . "<br />" .
     "Longitude: " . $record->longitude . "<br />" .
     "Metro Code: " . $record->metro_code . "<br />" .
     "Area Code: " . $record->area_code . "<br />" ; 

geoip_close($giCity);

?>

3. 国家名称：沙特阿拉伯
4. 区域代码：
5. 城市：
