Taking first value from the form data(input)

$first_city = $_REQUEST['first_city'];

    "Полтава" => "важливий історичний центр, великий транспортний вузол України",
    "Маріуполь" => "значний порт і промисловий центр України",
    "Дніпро" => "місто в Україні на обох берегах річки Дніпро");

    echo "Done";

The result must be "Done". I write one from dict keys of $cities into input form on website and nothing print.Help plzzz.Maybe i miss smth..


The user is entering spaces around the city name. Remove them with trim().

$first_city = trim($_REQUEST['first_city']);
