通過包來安裝，點下面鏈接，注意看里面信息也有demo https://packagist.org/packages/geoip2/geoip2#v2.13.0 我是項目更目錄通過以下命令安裝 ~~~ composer require geoip2/geoip2:~2.0 ~~~  安裝比較簡單，主要是拿到那個地區數據庫，demo里面 ~~~ $reader = new Reader('/usr/local/share/GeoIP/GeoIP2-City.mmdb'); ~~~ GeoIP2-City.mmdb這個就是數據庫 供應商有收費和免費的，我們用免費就好，特別精準就要收費的，需要在這個網站注冊個賬號，隨便填 https://www.maxmind.com/en/accounts 注冊成功后可以到這里下載你需要的數據庫，數據庫是離線的，可能過個幾年數據就比較老了,需要更新，如果不想注冊不拿最新的話，網上下載的也是老的，定位省份城市不準，我試過了， demo也提供自動更新，但是我比較趕時間，目前用的還可以，就不搞了，不然下次再手動下載一份替換即可  文件下載之后，用后綴.mmdb的文件就好 ，以下是我的代碼，tp6框架 ~~~ public function getIpAddress($last_ip) { if (empty($last_ip)) { return ''; } try { $reader = new Reader(app()->getRootPath()."/public/xxxx/GeoLite2-City.mmdb"); $record = $reader->city($last_ip); // $country = empty($record->country->names['zh-CN'])?(empty($record->country->name)?'':$record->country->name):$record->country->names['zh-CN']; // $province = empty($record->mostSpecificSubdivision->names['zh-CN'])?(empty($record->mostSpecificSubdivision->name)?'':$record->mostSpecificSubdivision->name):$record->mostSpecificSubdivision->names['zh-CN']; // $city = empty($record->city->names['zh-CN'])?(empty($record->city->name)?'':$record->city->name):$record->city->names['zh-CN']; $country = $record->country->name??''; $province = $record->mostSpecificSubdivision->name??''; $city = $record->city->name??''; return $country.'
