PHP itself does not have any facility for running things according to a
schedule in the way you describe.  It looks like you need to run some
additional software using cron (or your operating system's equivalent).
Unix systems have a command called "at" which can be used to execute
things at specific times, but what it actually executes is still a
problem.  If you want to be able to launch programs on external
machines, there are security issues which must be addressed as well.

And what does "centian" mean?
