Quack - oops. Thanks for playing.

There's nothing to stop you writing a daemon in PHP. Although if it's not a
server process I'd use cron as well.

There are some (non-PHP) tools out there which are designed for exactly this
purpose. Some intercept the writes, some poll changes - either way, these
might be a more sensible starting place then cron (they will (appear to)
operate synchronously with the event). Check out dazuko, FAM and Gamin
