What is the difference between replacing data and updating data in this
sense?

What you might want to do with your array (which in PHP can also function
as a hash, with string indices) is create a wrapper class that kind of
emulates a hash tied to the DB like one might do in Perl, so that whenever
you 'store' a value in the array (via a method), it will automagically
update or insert into the underlying database.  PHP doesn't do ties
explicitly, but you can emulate this behaviour with a PHP class.
