FIFO/LIFO funtion/class on CI

[eluser]Subekti Pranoto[/eluser]
suppose there is TABLE `inventory' (`RecId` varchar(15), `code` varchar(15), 'price' int(21), 'quantity' int(11))

Are there any code on CI (library/ helper) that can handle FIFO/LIFO function, for inventory purpose?

Not that I know of. Should be simple enough to implement yourself in your model.

Seems assigning an auto-incrementing index for each item placed in inventory makes it simple enough to get the max index (LIFO) or the min index (FIFO).
