How to make weather forecast dynamically in php?

Question

PHP

Hello!
For the weather informer, I use the service api - https://openweathermap.org/
The code is like this

<?
$apiKey = "key";
$cityId = "Минск";
$googleApiUrl = "http://api.openweathermap.org/data/2.5/weather?q=" . $cityId . "&lang=ru&units=metric&APPID=" . $apiKey;
$ch = curl_init();

curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $googleApiUrl);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($ch);
curl_close($ch);
$data = json_decode($response);
$currentTime = time();
?>

The question is, how can I get the city dynamically?
I want to make static pages with cities on wordpress and load the weather forecast there
