Unset cookies php

Question

I have this code that setted when login check is fine:

if((isset($_POST[\"remember_me\"]))&&($_POST[\"remember_me\"]==1))
    {
    setcookie(\'email         


        

Answer 1

You need to set your expire time to the past, e.g.

setcookie('email', '', time()-3600);

Also you should be using an Absolute URI for your header('Location:' ....).

Answer 2

setcookie('cookiename', '', time()-3600);

Answer 3

either use the superglobal _COOKIE variable:

unset($_COOKIE['mycookiename']);

or call setcookie() with only the cookies name

setcookie('mycookiename');

To reset your cookies at logout use:

setcookie('pass');
setcookie('email');

For you login check:

if(
  isset($_POST["remember_me"]) &&
  $_POST["remember_me"]==1  &&
  $_COOKIE['pass'] != NULL &&
  $_COOKIE['email'] != NULL &&
)

Answer 4

To unset cookies in PHP, simply set their expiry time to a time in the past. For example:

$expire = time() - 300;
setcookie("email", '', $expire);
setcookie("pass", '', $expire);

Answer 5

try this

    setcookie ("email", "", time() - 3600);
    setcookie ("pass", "", time() - 3600);

Answer 6

In Chrome and IE8+ at least, the following will remove the cookie from the browser. It will not be reflected in the $_COOKIE array until the page is reloaded however.

setcookie('cookiename','',0,'/',$cookieDomain)

you may be able to leave off a few parameters here, but the important thing is you are setting an empty string, and that removes the cookie from the browser.
