cookie value in php dosen't change - php

Question

I have a big problem in changing cookie value. I have buttom function to change(if exist)/create(if !exist) cookie and set value for it.
When i call function the session value changed, but not happened any change in cookie data.
function setToken($time = 0) {
global $value;
if (!isset($_COOKIE["name"])) {
setcookie("name", $value, time() + $time);
} else {
$_COOKIE["name"] = $value;
}
$_SESSION["name"] = $value;
}
What's wrong && What's should i do???

Answer 1

Assigning to the $_COOKIE global doesn't actually set the cookie in the browser. Always call setcookie.
Also, make sure that no content has been sent to the browser before you set the cookie. Cookies are set in the headers sent to the browser so cannot be set after content has started to be flushed.

Answer 2

From the manual:
Cookies will not become visible until the next loading of a page that
the cookie should be visible for. To test if a cookie was successfully
set, check for the cookie on a next loading page before the cookie
expires. Expire time is set via the expire parameter. A nice way to
debug the existence of cookies is by simply calling
print_r($_COOKIE);.
Update:
Your code works for me. But make sure you give a positive integer to your function setToken(). If you do not, the cookie will be immediately expired and not be shown!
If you want to change the cookie value, change your code:
function setToken($time = 0) {
global $value;
if (!isset($_COOKIE["name"])) {
setcookie("name", $value, time() + $time); // inital set
} else {
setcookie("name", $value); // change value
}
$_SESSION["name"] = $value;
}
