Я написал урок, основанный на ответе «Чандра Накка». Надеюсь, это может помочь людям, так как сохраняет информацию из геоподключаемого модуля в сеанс, поэтому загрузка при вызове информации происходит намного быстрее. Он также сохраняет значения в частном массиве, поэтому вызов в том же коде является самым быстрым из возможных.

Отвечая на вопрос "op" с этим классом, вы можете позвонить
$country = (new \Geo())->get('country'); // United Kingdom
И другие доступные свойства:
$geo = new \Geo('185.35.50.4');
var_dump($geo->get('*')); // allias all / location
var_dump($geo->get('country'));
var_dump($geo->get('countrycode'));
var_dump($geo->get('state')); // allias region
var_dump($geo->get('city'));
var_dump($geo->get('address'));
var_dump($geo->get('continent'));
var_dump($geo->get('continentcode'));
var_dump($geo->get('request'));
var_dump($geo->get('latitude'));
var_dump($geo->get('longitude'));
var_dump($geo->get('accuracy'));
var_dump($geo->get('timezonde'));
var_dump($geo->get('currencyCode'));
var_dump($geo->get('currencySymbol'));
var_dump($geo->get('currencySymbolUTF8'));

$real_ip_addressвсегда игнорируется. В любом случае помните, что HTTP-заголовокX-Forwarded-Forочень легко подделать, и что существуют прокси, такие как www.hidemyass.com - person Walter Tross schedule 30.03.2014https://www.iplocate.io/api/lookup/8.8.8.8- Отказ от ответственности: я запускаю эту службу . - person ttarik schedule 15.11.2017
