yii 2フレームワークでgeoipを使用する拡張に適合

 main.php 
'ip2location' => [
            'class' => '\client\components\IP2Location\Geolocation',
            'database' => '/data/www/html/httpserver/vendor/ip2location/ip2location-php/databases/IP2LOCATION-LITE-DB1.BIN',
            'mode' => 'FILE_IO',
        ],

実装されたコードは次のとおりです.

    /**
