missed a couple of quotes and braces there :)

Hi
I would do it this way (untested)
while ($row = mysql_fetch_assoc($result)) {
$vehicles[$row['dealer_id][$row['vehicle_id]['views'][] =
$row['page_views'];
}
should end up something like this
(
[645] => Array
(
[35073] => Array
([
dealer_id']][$row['vehicle_id']][$row['company_id']]

so you'd get something like (manually created result...):
(
[645] => Array
(
[35073] => Array
(
[1] => 10
[0] => 6
)
)
)

As you can see, it's hideously simple and not optimized in the least.
It works well on small datasets, but you can see by looking at it that large
datasets get exponentially slower.

it, which is why I thought I'd ask. =)

this sort of merging would be easier to do when you create the array
(unless you need the other format for something else?)
