looping through an object twice - php - php

Question

I'm playing around with a zencart trying to make it do what I want but I've run out of ideas of what to Google.
When I query the DB using the zencart function the software returns an object which looks like:
queryFactoryResult Object
(
[is_cached] =>
[resource] => Resource id #117
[cursor] => 11
[EOF] =>
[fields] => Array
(
[products_id] => 5582
[products_description] => description here
[products_name] => Lucky magnet – Each petal...
[products_type] => 1
[products_quantity] => 0
[products_image] => EachPetalMag.jpg
[products_price] => 3.4000
[products_status] => 1
[products_ordered] => 14
[master_categories_id] => 21
[supplier_id] => 7
)
)
I have to loop through once to count how many master_categories are there before I can do anything else:
while (!$products->EOF) {
$products_count++;
$supcats[$products->fields['master_categories_id']] = $products->fields['master_categories_id'];
$products->MoveNext();
}
I then need to loop through the object again using the while loop like above, I've tried:
reset($products);
and
$products->EOF = FALSE;
but they don't work. Is there a way to do this with out having to send the query again?

Answer 1

Regular array-like operations on Zen Cart queryFactoryResult won't work as it's not an array, so this won't work:
reset($products);
To loop through the variable again use queryFactoryResult->Move(row_number) method:
$products->Move(0);
