*Combining* duplicates in an array
I have an array like this, created from a MySQL result set:
There can be multiple rows with an identical $item_id and I'd like to create a new array with all the values intact, but with items of the same $item_id combined into one with a TOTAL of the $item_count.
$items = array(
"item_id" => $item["ID_ITEM"],
"item_count" => $itemfinal["BUNDLE"],
// other values here
Despite my efforts to figure it out, I'm afraid I'm stumped as to how to do that.
Thank you in advance for your help.
