Look this solution:
//$data - your array
$result = [];
foreach ($data as $item) {
$result[$item['order_id']]['qty'][] = $item['qty'];
$result[$item['order_id']]['sell_price'][] = $item['sell_price'];
$result[$item['order_id']]['product_name'][] = $item['product_name'];
$result[$item['order_id']]['merchant_name'][] = $item['merchant_name'];
}
// $result your result array
