how to iterate through a particular part of an object - php

Question

I have an object which looks like this
zen_categories_ul_generator Object
(
[root_category_id] => 0
[max_level] => 6
[data] => Array
(
[0] => Array
(
[19] => Array
(
[name] => Brushes
[count] => 0
)
[29] => Array
(
[name] => Clips
[count] => 0
)
[2] => Array
(
[name] => Combs
[count] => 0
)
[27] => Array
(
[name] => Jewellery
[count] => 0
)
)
[1] => Array
(
[57] => Array
(
[name] => Testing
[count] => 0
)
)
And I want to loop through all the information at the level $this->data[0], I'm using
foreach($this->data[0] as $category_id => $category) {
$result .= $category_id.' - '.$category['name'];
}
return $result;
but this will just the last item in the array. so in this case it would only have 27 - Jewellery but none of the other array item would be returned.
What am I doing wrong?
thanks
NB I only need to loop through the data[0] - not data[1] as well!
EDIT - here's a paste bin with a more code to make easier to understand what I'm trying to do and how I'm doing it. Any help gratefully received

Question:
Ok, so you want to loop through all the information $this->data[0], to render a menu.
Actually, you were pretty close to the solution, yourself.
The line used for rendering the product items, is:
$result .= ''.$category['name'] . ' (' . $category['count'] . ')';
The following is working example, which works standalone.
You might save it as menu.php and test it.
I had to comment the zen_* function out, but i think the relevant part is the rendering, right?
class zen_categories_ul_generator
{
function setTestData($data) { $this->data = $data; }
function buildMenu() {
$result = '';
// removed home link, unchanged and not important in this example
// submenu
$result .= '<li class="submenu">';
$result .= 'Products';
$count = 0;
foreach($this->data[0] as $category_id => $category) {
$count++;
$result .= '<ul class="level2">';
$result .= '<li class="submenu">';
//$result .= ''.$category['name'].''.$count;
$result .= ''.$category['name'] . ' (' . $category['count'] . ')';
$result .= '</li>';
$result .= '</ul>';
}
$result .= '</li> Items:' . $count;
return $result;
}
}
$object = new zen_categories_ul_generator;
// ok, lets add your example data from outside to the object, in order to test the rendering
$data = array(
0 => array(
19 => array('name' => 'Brushes', 'count' => 5),
29 => array('name' => 'Clips', 'count' => 2),
2 => array('name' => 'Combs', 'count' => 1),
27 => array('name' => 'Jewellery', 'count' => 3)
)
);
$object->setTestData($data);
// render the menu
echo $object->buildMenu();
Result
Count is the number of iterations = the number of Products in a Category.
And the counter behind the product name is from the array, the key "count".
