I have written a function within locale.module to display a block with hyperlinks that I want to use to set cookies similar to the following:

$path = preg_replace("/.+\/\/[^\/]+(.*)/", "\$1/", $base_url);
setcookie("locale", 'en', time() + 3600 * 24 * 365, $path);

Can anyone explain how to set such a cookie - e.g. the format of the link and the required location of the code above?
