If you want to clean/delete the $_COOKIE variable:

// unset cookies 
if (isset($_SERVER['HTTP_COOKIE'])){ 
  $cookies = explode(';', $_SERVER['HTTP_COOKIE']);
  foreach($cookies as $cookie) { 
    $parts = explode('=', $cookie); 
    $name = trim($parts[0]);
    setcookie($name, '', time()-1000);
    setcookie($name, '', time()-1000, '/'); 
  }
}

If you just want to delete a specific cookie (for example $_COOKIE["cookie"]):

if (isset($_COOKIE['cookie'])) { 
  unset($_COOKIE['cookie']); 
  setcookie('cookie', '', time() - 3600, '/'); 
  // empty value and old timestamp 
}

In the first case, wouldn't it just be easier to do `foreach($_COOKIE as $key=>$value) { setcookie($key,'',time()-1000); }`? – Niet the Dark Absol Nov 27 '16 at 11:52

Here is a solution:

foreach($_COOKIE as $cookie)
{
    unset($_COOKIE[$cookie]);
}

Off the top of my head, I cannot see what the problem with that is?

caution: mind that the cookie value in you current $_COOKIE variable might stay unchanged by setcookie(), you will eventually need to unset it separately with unset($_COOKIE[$cookie_name]);
