setcookie() states "cookies must be sent before any other headers are sent (this is a restriction of cookies, not PHP).

http://www.php.net/manual/en/function.setcookie.php

I would like to suggest this is a restriction of PHP, not cookies.

I can send and read cookies right in the middle of my HTML
when I use Javascript: http://www.collegeSherbrooke.qc.ca/languesmodernes/cookie.htm

<script>

setCookie("TestCookie","first time",expdate);
var DisplayData = getCookie("TestCookie");
document.write(DisplayData);

document.write("<br>");

setCookie("TestCookie","second time",expdate);
var DisplayData = getCookie("TestCookie");
document.write(DisplayData);

</script>

When can we expect a feature change on setcookie() ?

this is because JS has dircet access to the browser., whereas PHP has not. it is a limitation of HTTP in general and cookies in particular. so the docs are right. no bug -> bogus

Javascript cookies are client-side which is an entirely different thing. If you want to get around header() and setcookie() limitations, take a look at http://www.php.net/manual/en/ref.outcontrol.php

Exactly, PHP is server-side... So this is a restriction of the server-side theory. Javascript is a client-side browser controlled language, it is not executed on the server at all.

Ok, but how many times do you have to press submit before the browser actually acts. Click #1 sets the cookie, click #2 is able to read the cookie change. 1 click too many in my opinion.

You only need one click.  set, click, read (tm).
