permanent cookie

Anon

Hi,

how can I set a permanent cookie that never expires ?

Thanks for your answers.

Anon

setcookie ( "CookieName", "Value", 0, "/", "", 0 );

This cookie will not expire.

I tested your code and it doesn't seem to work.

In a page (cookie.php4), I have this code :

<?
$memberid=123;
if (!isset($my_memberid))
setcookie("my_memberid", $memberid, 0, "/", "", 0);
?>

And in another page (cookie2.php4), I have :

<?
if (isset($my_memberid))
echo "memberid=$my_memberid";
?>

I first call cookie.php4 to set the cookie. Then, I call cookie2.php4 and it works (it displays "memberid=123").

But, if I close my browser (IE5) and I call directly cookie2.php4, it doesn't display the cookie value.

How can I keep the cookie permanent ?

What you can do if that does not work is to set the expire argument, the third one to a big number eg a year.( 3600 24 365 ).

Yes, that is what I finally did.

But it would be better to be able to set a cookie with an infinite expire time.

Anyway...

Many thanks.

But it would be better to be able to set a
cookie with an infinite expire time.

The RFC's and Netscape Cookie Spec say you can't, so you can't.

And AFAIK, the maximum cookie lifetime in all browsers is a year - if you try and set it any higher, it'll either a) be set for a year; b) be set with no expiry (will die when the browser is closed); or c) not be set at all.

The only way to set an infinite cookie is to reset it every time the page loads.
