Create unset cookie button

I have created a cookie using php and now I need to create a button the user can click to log out.

This would be the php code to unset the cookie: 

 unset($_COOKIE['access_token']);

But I'm a quite stuck with how to make the button functionality. Can anyone help me with it?

Thanks a lot

It's actually best to do:

setcookie("myCookie", null, 1); //# This will expire / delete *immediately*

If you use

setcookie("myCookie", null, 0), the cookie is still valid until they close their browser.

By the way you can delete cookie by setting time in past

setcookie($_COOKIE['access_token'],'',time()-3600);

you should unset session

session_destroy()'
