Answer 1

You could use this function to copy multidimensional arrays containing objects.

 $val ) {
        if( is_array( $val ) ) {
            $result[$key] = arrayCopy( $val );
        } elseif ( is_object( $val ) ) {
            $result[$key] = clone $val;
        } else {
            $result[$key] = $val;
        }
    }
    return $result;
}
