Populate Latitude and Longitude in the database from the user's IP - php

Question

I have a "users" table with columns:
Id | user_id | name | ip_address | lat | lng
The id column, user_id, name and ip_address have been populated, and now have 100k users.
The lat (latitude) and lng (longitude) columns have now been created, and I need them populated from the IP (you can not get the geolocation of the user).
I do not want precise location, just the approximate location, so what I need is a script that picks up the IP of each user, somehow extracts the latitude and longitude, and inserts into the database.
I have looked at "http://www.geoplugin.net/xml.gp?ip=" and "http://ip-api.com/json/" but I have no idea how to use api for 100k of users, nor PHP or mysql code, or shell to do this.
I am using only PHP, MySQLi with MySQL database. The application will display a list of users "nearby" (within a 100miles radius).
Excuse me, I'm very new to programming and I really do not know how to solve this.
Edit:
I just created an api that returns me all user_id and their respective IPs in an array.
Just being 105k of records, for being json, it was light but I did not want to share json publicly here because it would be the same as explaining my users' data.
 
the result of api is something like this:
{
     "api_status": 200,
     "ips": [
         {
             "user_id": "1",
             "ip_address": "177.198.86.7x"
         },
         {
             "user_id": "21",
             "ip_address": "177.18.246.9x"
         },
         {
             "user_id": "52",
             "ip_address": "177.36.60.1x"
         }
     ]
}
I am using the following function to return my data in php
function List_ip() {
global $sqlConnect, $db;
if ($db['loggedin'] == false) {
return false;
}
$ips = mysqli_query($sqlConnect, "SELECT `user_id` , `ip_address` FROM " . T_USERS . " WHERE `active` = '1'");
while ($fetched_data = mysqli_fetch_assoc($ips)) {
$list_ip[] = array_map('utf8_encode', $fetched_data);
}
return $list_ip;
}

I don't have much idea about limiting the number of requests, but try the below code to get the details from ip-api.
$url = "http://ip-api.com/batch";
$headers = array('Content-Type: application/json');
$fields = '[{"query": "208.80.152.201"}, // You can add multiple IP address in the same format.
{"query": "8.8.8.8"},
{"query": "24.48.0.1"}]';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_POSTFIELDS, $fields);
$httpCode = curl_getinfo($curl , CURLINFO_HTTP_CODE);
$response = curl_exec($curl);
if ($response === false)
$response = curl_error($curl);
foreach(json_decode($response) as $value){
echo $value->lat; //Use the result to store the information in DB
}
curl_close($curl);
Refer their documentation to get an idea about the data returned by their API.

The maxmind/GeoIP2-php should get you want you need.
Install it and download the GeoIP2-City.mmdb file.
Than just a matter of initiating it:
$record = new Reader('path/to/GeoLite2-City.mmdb');
and reading the data from it, such as:
$city = $record->city->name;
$latitude = $record->location->latitude;
$longitude = $record->location->longitude;
Doing it this way will mean zero dependency on third-party API limitations.

What you are asking for requires intermediate skills with PHP and MySQL etc.. I have done many things like this, and will tell you that firstly to get accurate GEO IP information you will have to use javascript or pay for a service (from my findings). For example www.maxmind.com has a free and pay, the pay is a bit better.
What I would do is try writing a script that reads all of the users out of the database in a loop, then download geopip or use an api to take the IP fields and return the Lat/Lon. Then finally add the step that writes it back to the DB .
A very rough example:
// build a class or function that looks up IP addresses (can be local)
$geoip2 = new GeoIp2Lookup(true);
// get all users from DB
$allUsersArray = function_results_db_lookup_users();
// get the users lat/lon
for ($i=0; $i<count($allUsersArray); $i++) {
$record = $geoip2->getGeoDataArr($allUsersArray[$i]['ip_address']);
$allUsersArray[$i]['lat'] = $record['lat'];
$allUsersArray[$i]['lon'] = $record['lon'];
}
// now write a function to place in DB the new data
update_users_db($allUsersArray);

You can easily use the IP2Location PHP Module at https://www.ip2location.com/development-libraries/ip2location/php which is free.
To install, add the below line into your composer.json file.
{
"require": {
"ip2location/ip2location-php": "8.*"
}
}
Run the command:
composer install
Note: You just need to include the below code in order to use the library.
require 'vendor/autoload.php';
You'll need the DB5.LITE database which you can download for free at https://lite.ip2location.com/
Example usage of the PHP module
<?php
require 'IP2Location.php';
$myip = '8.8.8.8';
$db = new \IP2Location\Database('./database/IP-COUNTRY-SAMPLE.BIN', \IP2Location\Database::FILE_IO);
$records = $db->lookup($myip, \IP2Location\Database::ALL);
echo '<pre>';
echo 'IP Address : ' . $records['ipAddress'] . "\n";
echo 'Country Code : ' . $records['countryCode'] . "\n";
echo 'Country Name : ' . $records['countryName'] . "\n";
echo 'Region Name : ' . $records['regionName'] . "\n";
echo 'City Name : ' . $records['cityName'] . "\n";
echo 'Latitude : ' . $records['latitude'] . "\n";
echo 'Longitude : ' . $records['longitude'] . "\n";
echo '</pre>';
?>
