If you are trying to paginate an array of data, just use array slice (). it takes the same offset and length values as the limit clause in an sql query would. this would eliminate all this 'glue' logic. you would just foreach () {} loop over the array of data returned. this will also work correctly for a partial last slice or an initial slice.
