Deleting cookies

You can not delete a cookie, but you can assign it a different value from what it
should be to permit some action.

The easiest way you can use this script is to link it to a "Log off" button or link:


<?
//Killing the cookie:
$cookie_name="myCookie";

//here we assign a "0" value to the cookie, i.e. disabling the cookie:
$cookie_value="";

//When deleting a cookie you should assure that the expiration date is in the past,
//to trigger the removal mechanism in your browser.
$cookie_expire=time()-60;

$cookie_domain="";
setcookie($cookie_name, $cookie_value, $cookie_expire, "/", $cookie_domain,0);

//re-direct to login screen (or any other you like):
header( "Location:login.html");
exit;
?>
