I am using MVC with PHP/MySQL.

Suppose I am using 10 functions with different queries for fetching details from the database.
But at other times I may want to get only the count of the result that will be returned by the query.
What is the standard way to handle such situation.
Should I write 10 more functions which duplicate almost whole query and return only the count.
Or
Should I always return the count also with the result set
Or
I can pass a flag to indicate that the function should return count only, and then based on the flag I will dynamically generate the (select part of) query.
Or
Is there a better way?
