Cookie设置与旧值

Question

I'm using the code:

IF (isset($_GET['s']))
{
    $sessie = $_GET['s'];
}
ELSE
{
    $sessie = 'I';
}
$cookie = 'JaiDje_Page';
setcookie($cookie, $sessie);
$WDpag = $_COOKIE[$cookie];
echo $WDpag."-".$_COOKIE[$cookie]."-".$sessie."<br>";

After a new value for $sessie (menu choise) the strange thing is that the first time the page is loaded, $WDpag and $_COOKIE[$cookie] are giving the old value and $sessie is giving the new value. After a page refresh all three values are the same.

So after making a choise in the menu the following is echos (exampel)

I-I-Z

than after a page refresh (F5)

Z-Z-Z

It seems that the cookie is one step behind the choise in my menu.

What am I doing wrong?

Answer 1

$_COOKIE is set when the page loads so If you want immediate access, you can set $_COOKIE['variable'] direct.

so do like this

//setcookie($cookie, $sessie);
$_COOKIE[$cookie] = $sessie;
