$_COOKIE is set when the page loads, due to the stateless nature of the web. If you want immediate access, you can set $_COOKIE['uname'] yourself or use an intermediate variable.

For example:

if (isset($_COOKIE['uname'])) {
    // get data from cookie for local use
    $uname = $_COOKIE['uname'];
}
else {
    // set cookie, local $uname already set
    setcookie('uname', $uname, time() + 1800);  
}
