在可变时间执行脚本

Question

I'm aware of cron jobs to execute commands at a certain time, but what if that time is not constant? For instance, suppose a user asks for a reminder email exactly 1hr after signing up for something, is there an easy way to go about doing this?

Timing is critical. I am actually trying to create AI that will essentially act on its own but only at variable points during the day. Any help would be appreciated!

Answer 1

Here a workable flow:

1. user Requests email in 1 hour
2. You insert into the a table action (action_id, time)
3. On the PHP server create a cron job to check the action in the action table every minute, then do the action that need to be done at that time

That is a simple example from the request. It might get a bit more complex then that.

EDIT : this suggestion might be good only if you need to be very precise with the time management!
