Will there be a way to output lists, categories and interests?

[latestscoop]

Currently I am using the following class:

class MailChimp_Extend extends MailChimp {
	/*
	Returns structure array: list > category > interest
	*/
	public function get_structure(){
		$lists = $this->get('lists');
		//print_r($lists);
		$structure = array();
		foreach($lists['lists'] as $list){
			$this_list_id = $list['id'];
			$this_list_name = $list['name'];
			$structure[$this_list_id]['id'] = $this_list_id;
			$structure[$this_list_id]['name'] = $this_list_name;
			$structure[$this_list_id]['categories'] = array();

			$categories = $this->get('lists/' . $this_list_id . '/interest-categories/');
			//print_r($categories);
			foreach($categories['categories'] as $category){
				$this_category_id = $category['id'];
				$this_category_name = $category['title'];
				$structure[$this_list_id]['categories'][$this_category_id]['id'] = $this_category_id;
				$structure[$this_list_id]['categories'][$this_category_id]['name'] = $this_category_name;
				$structure[$this_list_id]['categories'][$this_category_id]['interests'] = array();

				$interests = $this->get('lists/' . $this_list_id . '/interest-categories/' . $this_category_id . '/interests');
				//print_r($interests);
				foreach($interests['interests'] as $interest){
					$this_interest_id = $interest['id'];
					$this_interest_name = $interest['name'];
					$structure[$this_list_id]['categories'][$this_category_id]['interests'][$this_interest_id]['id'] = $this_interest_id;
					$structure[$this_list_id]['categories'][$this_category_id]['interests'][$this_interest_id]['name'] = $this_interest_name;
				}
			}
		}
		//print_r($structure);
		return $structure;
	}
}

Using it like this:

$MailChimp = new DrewM\MailChimp\MailChimp_Extend('key');
$structure = $MailChimp->get_structure();
print_r($structure);

Which putputs an array:

Array(
    ["list id"] => Array(
            [id] => "list id"
            [name] => "list name"
            [categories] => Array(
                    ["categoy id"] => Array(
                            [id] => "categoy id"
                            [name] => "categoy name"
                            [interests] => Array (
                                    ["interest id"] => Array(
                                            [id] => "interest id"
                                            [name] => "interest name"
                                    )
                                    ["interest id"] => Array(
                                            [id] => "interest id"
                                            [name] => "interest name"
                                    )
                            )
                    )
            )
    )
);

...where the double-quotes are actual ids and names.

I use it to dynamically create checkboxes in forms, whenever categories/interests are amended.
I would imagine if you're using Mailchimp groups and this API, you would need to generate group checkboxes at some point.
