    I have a question about how to store/save input arrays on function `function update($instance, $old_instance) {

    My input field looks like this
    <input type="text" id="image_url" name="image_url[]" value="" />
    Normally you save it like this
    $instance['image_url'] = $new_instance['image_url'];
    But how do i save it if i want to make use of input array?
