PHP Cookie question!

Hello,
I am trying to create a logout function in my cart. I checked back at other posts to see how this is done, but it doesn't seem to work. Here's how I am attempting to do it:
header("Set-Cookie:user=null;");
setcookie("user", "null");
However, it doesn't clear or erase the cookie! Ideas?
Thanks for your help,
Joseph |

The key is, you have to clear the cookie the same way you set it.
I set the cookie like this:
header("Set-Cookie:password=PASS;expires=Friday, 16-Jan-2037 00:00:00 GMT");
Then I clear the cookie like this:
header("Set-Cookie:password=;expires=Friday, 16-Jan-2037 00:00:00 GMT");
Notice it is identical, except for the value of password. That works for me.

You could also set the expiration date to a value in the past. Then the browser would immediately expire the cookie and delete it. You could either use the header() function, or use setcookie() to do the same thing, just with an easier syntax. You would use:
setcookie("password", "", time() - 3600); // Set the expiration date to an hour ago.
Besides clearing the password, it would also delete the cookie from the user's browser.
