$_COOKIE question

[dhimok]

Hello everyone. I have this question

 

Is it possible to control cookies from my own domain stored on users computers? I wonder if I can change the expiry date, increase or decrease or delete them, while they are already set from before

 

Thanks

Yes you can, very easily too.

I would like to add some more details:

 

Lets say I store a cookie when a user enters my page that will expire in 1 year. Next time the same user enters the page it wont set the cookie again, unless its not there. Now I want that cookie which is stored to expire in 3 days. Is this possible and if yes then how

i think before you learn to modify something you should learn how to make it.

This is what I did. I think its ok

 

if(!isset($_COOKIE["uid"])) {
$uid =  sha1(session_id().@time()); 
$expire1 = 365*24*3600; // 1 year
setcookie("uid", $uid, (time() + $expire)); 
} else {
$expire2 = 7*24*3600; // 1 week;
setcookie("uid", $_COOKIE["uid"], (time() + $expire2)); 
}

 

Any other ideas would be appriciated
