I'm assuming you also need all of the Entry objects, for some reason
that you did not mention? Because, clearly, if you didn't need all of
the Entry objects, you could just get the EntryMeta objects that you
want with a JOIN statement. But, assuming you need the extra data for
some other reason, you could use a built-in PHP function, like
array_walk(), to look through the array of Entry objects that were
returned from database. I think this still involves a loop, but the
loop is no longer happening in your code, it gets moved to the innards
of array-walk().
