class AuthApache extends Apache {
	protected $stored_realm;
	public function setRealm($r)
	{
		$stored_realm = $r;

The assignment to $stored_realm is dead and can be removed.

	}
	public function challenge(RequestInterface $rq, ResponseInterface $rs)
	{
		$rs->addHeader("WWW-Authenticate", "Basic realm=$stored_realm");

The variable $stored_realm seems to be never defined.
