Not displaying correct out put on view - codeigniter

Question

I have two database tables called forum and forum_category.
In the forum table "General" and "Vegetables"
On the forum_categories there are two forum categories for General and one in Vegetables.
But for some reason my forum Vegetables is showing multiple categories should be only displaying one.
My question is how can I get the correct categories to display in
correct forum.
Note: It shows the correct results in the print_r image

Think I have the solution now
Solution
Placing $categories = array();
above $categories_results did the trick
public function index()
{
$results = $this->get_results();
foreach ($results as $result) {
$categories = array();
$categories_results = $this->get_result_categories($result['forum_id']);
foreach ($categories_results as $category_result) {
$categories[] = array(
'category_name' => $category_result['category_name']
);
}
$data['forums'][] = array(
'forum_name' => $result['forum_name'],
'categories' => $categories
);
}
$data['content'] = 'common/home_view';
$this->load->view('theme/default/template_view', $data);
}
