Set cron job php

Question

How can i set a cron job programatically ,

we made a installer for our project and on the installation time i need to set a cron job programatically with PHP.

Please note that the project can be running on LINUX/WINDOWS ,

how can i achieve that ? or is there any better option than CRON JOB.

I am using Codeigniter(Native php based solutions are always welcome , but it will be very helpful if it is through CI)

THE cron job includes

1. Check a particular table and remove invalid data
2. Insert values to DB from mailServer
3. Checking the availability of some files.

Thanks.
