What is the \"less code needed\" way to get parameters from a URL query string which is formatted like the following?

For getting each node in the URI, you can use function explode() to $_SERVER['REQUEST_URI']. If you want to get strings without knowing if it is passed or not. you may use the function I defined myself to get query parameters from $_REQUEST (as it works both for POST and GET params).

function getv($key, $default = '', $data_type = '')
{
    $param = (isset($_REQUEST[$key]) ? $_REQUEST[$key] : $default);

    if (!is_array($param) && $data_type == 'int') {
        $param = intval($param);
    }

    return $param;
}

There might be some cases when we want to get query parameters converted into Integer type, so I added the third parameter to this function.
