通过包来安装，点下面链接，注意看里面信息也有demo https://packagist.org/packages/geoip2/geoip2#v2.13.0 我是项目更目录通过以下命令安装 ~~~ composer require geoip2/geoip2:~2.0 ~~~  安装比较简单，主要是拿到那个地区数据库，demo里面 ~~~ $reader = new Reader('/usr/local/share/GeoIP/GeoIP2-City.mmdb'); ~~~ GeoIP2-City.mmdb这个就是数据库 供应商有收费和免费的，我们用免费就好，特别精准就要收费的，需要在这个网站注册个账号，随便填 https://www.maxmind.com/en/accounts 注册成功后可以到这里下载你需要的数据库，数据库是离线的，可能过个几年数据就比较老了,需要更新，如果不想注册不拿最新的话，网上下载的也是老的，定位省份城市不准，我试过了， demo也提供自动更新，但是我比较赶时间，目前用的还可以，就不搞了，不然下次再手动下载一份替换即可  文件下载之后，用后缀.mmdb的文件就好 ，以下是我的代码，tp6框架 ~~~ public function getIpAddress($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.'
