Manage crontab from php

I was thinking to manage crontab from ph开发者_开发技巧p so I ask you if exist a class that allow to create, edit, delete crontab from php? Or there is another method to create and manage cronjob from php?

I found a tutorial on this subject here

There are a number of existing classes and tutorials out there for this, but I can say that I've not seen a widespread defacto class that "everyone" uses.

The code would be rather trivial, though, and this may be why no popular class has emerged: there isn't much demand. Nothing stopping you from making one for your own toolkit.
