Using PHP to add/edit cronjobs

[mraza]

Hi,

Is there any way i can use a php script to edit crontab jobs. i use this command on my centos based server to add/edit cronjobs. . "crontab -e"

I wants to manage my cronjobs with a php file to add/edit cronjobs.

 

Thans for any help.

Of course. Look at the manual entry for crontab.

 

man crontab

Thank you sir , i checked manual and i see this

SYNOPSIS
       crontab [-u user] file

 

so for example if i execute in my php script

exec("crontab -u username -e cronjobfile.php");

 

will it use that cronjobfile.php to get cron jobs details? so i can add cronjobs to cronjobfile.php with my mysql db something, if you could show me a little bit of example i would really appreciate it sir.

 

Thanks again

do i need to save that file as somename.txt ?

so it contains lines of crontabs like

 

* * * * /path/to/my/file/to/run

* * * * /path/to/my/file/to/run

 

and where i will store that file somename.txt

 

Thanks for any help.

Hi, I have figured out how to add cron, i used

exec("crontab -f cronfile.txt);

Now i can see that cron is being added as apache user with this command:

crontab -u apache -l

 

 

Edit: fixed all thanks
