[fw-general] Zend_Acl howto know isAllowed is false due to assert fail?

[Julian Davchev]

Hi,
Lets say I have this snippet

....some code already for creating acl object....
$acl->allow('baby','house','break',$hadMilk);

So how do I know i
$isAllowed = $acl->isAllowed('baby','house','break');    

// so if $isAllowed === false    how do I know this is due to $hadMilk
assert is false or just no such allow rule there?
