use GeoIp2\Database\Reader;
$databaseFile = 'GeoLite2-City.mmdb';

{
    try {
        $reader = new Reader($databaseFile);
        $record = $reader->city($ip);
        if (
            $record->city->name === 'Jodhpur' 
        ) {
            return true;
        }
    } catch (Exception $e) {
        return false;
    }
    return false;

<?php
