While it would be absolutely trivial to add an artificial limit of 4K
or
any other arbitrary # as the maximum cookie length. This would not be
correct and has a good chance of breaking existing applications.

In my opinion it's up to the coder to decide what he allows to be put
in cookies set. If he/she does't bother doing any filtering or such for
and inserts blindly input data there, it's his/her fault..

ie7 increased the number of cookies per domain from 20 to 50, like
other browsers.
so why not limiting php to set max 20 cookies per domain like NS
"mention"?
Netscape also follow these rfc
if the client ignore part of the cookie it's not PHP concern.
what if I built an application follow the rfc and php artificially
limiting me?

also imagine the following code
setcookie ("foo", $_GET['reallybigdata'])
it can also exausts the PHP process or system memory(dependding on the
memory limit)for no gain because the browser will truncate it anyway.

PHP implements the netscape spec, **not** the RFC one
"When a cookie larger than 4 kilobytes is encountered the cookie should
be trimmed to fit, but the name should remain intact as long as it is
less than 4 kilobytes"
"Servers should not expect clients to be able to exceed these limits"
In the case of PHP, sending a cookie bigger than 4kb is useless because
no browser will use it correctly, and truncating it without emitting any
warning just makes debugging harder.

RFCS linked from the setcookie function docs
"
...
* at least 300 cookies
* at least 4096 bytes per cookie (as measured by the characters
that comprise the cookie non-terminal in the syntax
description
of the Set-Cookie2 header, and as received in the Set-Cookie2
header)
...
"
keyword:at least
so basicly php should not limit cookie length, it up to the
client/browser how to handle it.
