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

I think that you have to use combined approach:

• set expiration way back in the past (as suggested by Chacha102)
• use JavaScriptto delete entries from document.cookie DOM object (as suggested by andres descalzo)

There are 2 good reasons for going with mixed approach:

• JavaScript can be disabled in the browser
• not all cookies are visible in document.cookie Some modern browsers are supporting httponly flag for cookies. PHP has support for httponly cookies, see http://www.php.net/setcookie
