Hello,

im working with cron's more and more, and i would like to know if there is a easy way to a) retrieve the cron infomation, IE time and the script etc
and if possible edit, add, remove the cron jobs through PHP?

Is this possible and how would i go about doing it?
Thanks,
Dan

Nope, you're not going to be able to use PHP. It's all Linux commands.

Well could i used PHP to execute them using System/exec ?

cron its part of linux shell.

use c++ scripts for internal cron control.

Yer I'd stick with C++. I mean I guess you could use PHP somewhat but no matter what you're going to have to use more than PHP.

Does cpanel have any kind of api? so i could have the same kind of thing which cpanel has to manage crons but within my own site control panel.

Cron is a unix tool, right, but it's mostly aimed as being ran by the machine administrator account (though some implementation like Vixie allows users to have their own cron file) and so, letting PHP access it means that you remove any kind of security on the file.

Cron is the process, and it reads a crontab file (usually /etc/crontab).
Modify that file, and you change what cron does.
To allow the web server user to do that, means that you must make that file world writable.

Now, call me paranoid, but imagine a script kiddies breaking one account, and putting a

* * * * *  root rm -rf /

in your crontab...

I'm not really sure you would like to do that...

Okay i get you...

So would be complicated and i couldnt do it anyway without root access...

D'oh
