mr.hongphuoc,

This is not a bug, this is a pure PHP problem. You can access the cookies in the next load if you want to save the "LANG" as it was a cookie set it when you call the "setcookie" function, so:

Code:

if (!isset($_COOKIE['LANG']))
{
setcookie('LANG', 'en', time()+86500,'/','');
$_COOKIE['LANG'] = 'en';
}

Check PHP Manual for the setcookie: http://www.php.net/manual/en/function.setcookie.php, it says "Once the cookies have been set, they can be accessed on the next page load".

Best!

... and it's not PHP's problem either. Thats simply how cookies work:

Step 1: HTTP Client <request> HTTP Server
Step 2: HTTP Server <response> HTTP Client

This happens every time you visit a web page. When you call setcookie(), the cookie is sent in Step 2 as a part from the server's response. However, a cookie must be sent by the client (your browser) in Step 1, so that it's data can be available to the server, which happens on your next page load.
