Delete cookie from browser?

Question

Is there any way of instructing a web browser to completely delete one\'s cookie set with PHP?

I do not want to expiry it or wait for the brows

Answer 1

Try something like this to delete all cookies:

foreach ($_COOKIE as $name => $value) {
    setcookie($name, '', 1);
}

The value 1 is the expire value and it represents one second after the begin of the Unix time epoch. So it’s always already expired.
