Why Simple IP Geolocation Scripts Return Empty City Data

Simple IP geolocation snippets look deceptively easy: call an external endpoint, parse XML, print the city. But when the city comes back empty, the problem may not be your PHP syntax at all.

Typical script

$ip = $_SERVER['REMOTE_ADDR'];
$url = 'http://ipgeobase.ru:7020/geo?ip=' . $ip;
$xmlstr = file_get_contents($url);
$xml = new SimpleXMLElement($xmlstr);
$city = $xml->ip[0]->city;
echo $city;

Why the city may be empty

• The service has no reliable city data for that IP.
• The response encoding or structure changed.
• The request is made from a local, proxy, or provider-level address that maps poorly.
• The service itself is rate-limited or partially unavailable.

Practical takeaway

IP geolocation is useful as a hint, not a foundation for critical business logic. If a site depends on regional behavior, always provide a manual override and treat geolocation as a best-effort suggestion.
