Even if there is any kind of difference, that difference will be so small it won't matter at all.

If you have, say, one query to the database, it'll take so long compared to the loop iterating over the results that the eternal debate of for vs foreach vs while will not change a thing -- at least if you have a reasonable amount of data.

So, use :

whatever you like
whatever fits your programming standard
whatever is best suited for your code/application

There will be plenty of other things you could/should optimize before thinking about that kind of micro-optimization.

And if you really want some numbers (even if it's just for fun), you can make some benchmark and see the results in practice.
