To help you figure this out I would point you to the php manual. It says exactly where you should do it. In fact, where you HAVE to do it - "before any output is sent".

Do you mean, like, where is the most appropriate place in code to set it? There isn't anything in there that's clearly "this is a point where the user has chosen a particular language", but the closest would be where you check $_GET.

if (isset($_GET['language']) && self::is_language_supported($db, $config, $_GET['language'])) {
	// setcookie(...)
	return $_GET['language'];
}
