Within the following code, $quiz_object->personalities contains an array of Personality() objects.

// Loop through each personality that exists for the quiz
foreach($quiz_object->personalities AS $existing_personality)
{

    // Show all of the existing personalities
    echo $existing_personality->GetQuizMakerPersonalityHTML();
}

How do I "cast" (I think that's the right word) my variable $existing_personality within the foreach loop as the object type?

I wish to do this so that when I type $existing_personality->, I get the list of public functions available for that object type.

At the moment, Zend doesn't know that it refers to a Personality object within the loop.
