Automatic reminder help

[makundib]

I want to design a sort of two departments communication in such a way that one department will be incharge to foward/assign a job to the second one,and if it happen that the job is not completed within three[3] days the system is suppossed to generate an automatic reminder to alert the member of the other department about the job.
Im using php,MySql and Apache webserver.

PHP cannot run by itself automatically. So, either run it each time the user views the page and check if anything is older than 3 days at that point or use a cron job or something else on your site to make this happen.

Shouldn't be all that hard using a database. Here's a good tutorial:
