Ciao a tutti, sto seguendo un corso online ma non riesco ad uscirne.. mi esce questo errore:
Notice: Undefined index: city in C:\xampp\htdocs\Weather\index.php on line 3
<?php
if ($_GET['city']) {
$forecastPage = file_get_contents("https://www.weather-forecast.com/locations/Milan/forecasts/latest");
echo $forecastPage;
}
?>

La cosa divertente è che mi sembra uguale a quello che ha fatto il corso.. c'è qualche cosa che mi sfugge?
