PHP Array Values Not Leaving foreach Loop

Question

I am looping through a series of inputs and saving their values to an array. Each element in the array is a special class that has a name (so it can be uniquely identified) and an answer (initialized as null, populated in the following loop):

class Question
{
    public name;
    public answer;
}

...

foreach ($quiz_questions as $q)
{
    $inputName = $q->name;
    $response = $_POST[$inputName];
    $q->answer = $response;
    print_r($q->answer);
}
print_r($quiz_questions);

When I print each individual answer during the iteration, the values come out correctly, but when I print the entire array after the loop, the answer components are NULL like they were before the loop.

Any idea what the problem is?

As you say that each element in the array is a class, use the get_object_vars() function to access the class attributes.

get_object_vars($quiz_questions));

should do the work.
