Multiple cookies with the same name

Question

I just realized that I have a problem with IE, working from one of my pages. I set a cookie using

setcookie('page', '12345', '2000000', '/');

And if I log in I reset, the cookie calls this function again. Everything works fine in firefox because the old cookie is deleted, but in IE, both cookies remain? How can this happen? Isn't that illegal?

I have now fixed this with:

setcookie('page', '', time() - 3600, '/');
setcookie('page', '1234', '2000000', '/');

Is this normal, or am I missing something?

Answer 3

, session_start() , . JavaScript cookie, PHP. Internet Explorer, $_ENV [ "HTTP_COOKIE" ] cookie. Firefox.

, x.y.z Internet Explorer cookie x.y.z, cookie y.z. PHP cookie $_ENV [ "HTTP_COOKIE" ].

Perhaps this can be considered a PHP error, perhaps not. IMHO, this is an Internet Explorer bug. I post it here, hoping that it will help you solve your problem.
