Recommended by who? Here is a simple explanation why 1 is better than any of these mathematical calculations inside of setcookie command.

no don’t use unset() use setcookie()
the main unsuccessfull delete or expire cookie is because you made a cookie in dive folder inside host and you can’t delete in diferent folder outside you made and cookie path is set value already.

for better security and successfully use :
setcookie(“cookiename”,”",mktime(12,0,0,1, 1, 1990), “/”);

Don’t use unset($_COOKIE['variablename']). That will only unset the variable from the $_COOKIE superglobal array, it will not expire (delete) the cookie itself.

Somehow it seems you always need to know the ‘name of a cookie’…But if you don’t know this?

I am busy with protecting pages from a Wordpress website. Protecting works fine…but now I want provide a ‘log out’ button somewhere…but whatever I do…people stay logged in.

I want them to click on the ‘log out’ button and then end up on the startpage of the website…on which are 2 options: enter website – member login

All Javascript and PHP trickery I have tried always need the name of the Cookie.

And when I get the name of the Cookie (with the webdevelopers toolbar in Firefox) and put this in the right position…it never works,

Help is needed…sigh…

Only the following worked for me:

unset($_COOKIE['the_cookie_name']);

To delete a cookie by resetting it has severe and drastic limits.
I have found that when using PHP, after the header has had any output, you cannot ‘reset’ a cookie that way to make it expire.

In my opinion, a better way, (from a PHP programers’ view), is to use:
unset($_COOKIE['the_cookie_name']);

From my experience, doing it this way, you can delete a cookie anywhere within the PHP code without a problem and not restricted to when or where you delete it..
