I was happy to see you preparing and executing separately in your 'select'. I thought, oh good, but then when it really counted (inside a loop) I found you using $dbh->do(...).

You should be preparing your "updating" statement with placeholders, and then executing within your foreach loop. That's (1) more secure, and (2) faster.

That's just one "off the top of my head" area where you can improve.
