Question abt PHP variables by refernce & Zend_Auth
<p>its possible to do a </p>

<pre>$auth = Zend_Auth::getInstance();
$result = $auth->authenticate($adapter);</pre>

<p>but i thought that is not passing a variable by reference? </p>

<p>... or do i need to use the instance of Zend_Auth by instance anyway? </p>
