            [id] => 1

Answer 1

You need a little bit of recursion

function traverse_array($array)
{
    echo '
';
    foreach($array as $element)
    {
        echo '
';
        if(isset($element['comment']))
        {
            echo $element['comment'];
        }
        if(is_array($element['children']) && count($element['children']) > 0)
        {
            traverse_array($element['children']);
        }

        echo '
';
    }
    echo '
';
}

traverse_array($the_big_array);
