Well, it's kind of hard to explain, but what I want to do is something like having commands sent to the db w/o someone having to visit a page. ex: I want to have a db table emptied at a certain time every day.
How is that done? Thanks in advance.
Since I assume you know how to write a script to empty the DB, I would use PHP from the command line and run your script as a Cron job (a unix scheduler). The crontab will determine how often you'd like the script to run.
