Symfony with GeoIp2 - php

Question

HelloI need find city for ip, I install maxmind/GeoIP2-php and download file GeoLite2-City.mmdb 31mb GeoLite2-City.mmdb 2,2mb and create service AdditionalFunction and function getInfoIpCity, getInfoIpCountry and when developer registration I use this function like this:
$ip = $request->getClientIp();
$record = $hAid->getInfoIpCountry($ip);
$get_record = $hAid->getInfoIpCity($ip);
$record_coutry = $record->country->name;
I download GeoLite2-City-CSV_20150707/ and this file GeoLite2-City-Blocks-IPv4.csv 135.3 mb and in this file I find 176.241.128.0/20,690791,690791,,0,0,,50.4500,30.5233 If I have this file how I can find name city ? If I have in variable 50.4500,30.5233 and google know this is Kyiv how I get name city ?
and service:
class AdditionalFunction
{
private $rootDir;
public function setRootDir($rootDir)
{
$this->rootDir = $rootDir;
}
public function getInfoIpCountry($ip)
{
try {
$reader = new Reader($this->rootDir.'/data/GeoLite2-Country.mmdb');
$data = $reader->country($ip);
} catch (\Exception $e) {
$data = null;
}
return $data;
}
public function getInfoIpCity($ip)
{
try {
$reader = new Reader($this->rootDir.'/data/GeoLite2-City.mmdb');
$data = $reader->city($ip);
$m = $data->country->name;
$t = $data->country->isoCode;
$b = $data->mostSpecificSubdivision->name;
$c = $data->city->name;
} catch (\Exception $e) {
$data = null;
}
return $data;
}
}
coutry find right

I solved my problem I use free base for maxmind but if city not found in this DB I use googlr aip and find city for latitude & longitude, this code:
public function getInfoIpCity($ip)
{
try {
$reader = new Reader($this->rootDir.'/data/GeoLite2-City.mmdb');
$data_geo = $reader->city($ip);
$name = $data_geo->country->name;
$isoCode = $data_geo->country->isoCode;
$mostSpecificSubdivision = $data_geo->mostSpecificSubdivision->name;
$data = $city = $data_geo->city->name;
$postal = $data_geo->postal->code; // '55455'
$latitude = $data_geo->location->latitude; // 50.45
$longitude = $data_geo->location->longitude;// 30.5233
if (is_null($data)){
$url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng='.$latitude.','.$longitude.'&sensor=false';
$data = #file_get_contents($url);
$jsondata = json_decode($data,true);
if(is_array($jsondata )&& $jsondata ['status'] == "OK")
{
$addr = $jsondata ['results'][0]['address_components'][4]['long_name'];
$addr2 = $jsondata ['results'][0]['address_components'][4]['short_name'];
$addr3 = $jsondata ['results'][0]['address_components'][3]['long_name'];
}
$info = "Country: " . $addr . " | Region: " . $addr2 . " | City: " . $addr3;
$data = $addr3;
}
} catch (\Exception $e) {
$data = null;
}
return $data;
}
