AJAX Call to PHP file: return value is empty

Question

I have a simple ajax call:

function init() {
    $.ajax({
        url: \"./myFolder/user.php\",
        data: {
            action: \"init\"
        },
        t

On user.php page you need to do :-

function init() {
        $arr = array(
            array(
                "region" => "valore",
                "price" => "valore2"
            ),
            array(
                "region" => "valore",
                "price" => "valore2"
            ),
            array(
                "region" => "valore",
                "price" => "valore2"
            )
        );

        echo  json_encode($arr);
    }
