Using header() to delete a cookie.

[renegade888]

Hey everyone,

If you use the Set-Cookie http header in a header() call, how do you delete that cookie using the same method before it expires?

For instance, if I use:
header("Set-Cookie: username=$username; expires=time()+86400")
I would think that this would delete it:
header("Set-Cookie: username=$username; expires=time()-3600), but it doesn't do anything to the cookie.

Any thoughts?

Thanks in advance!

(read the manual)

use setcookie():

"If only the name argument is present, the cookie by that name will be deleted from the remote client."

so:

setcookie("MyCookie");

-> deleted
