Use PHP to create, edit and delete crontab jobs?

Question

Is it possible to use PHP to create, edit and delete crontab jobs?

I know how to list the current crontab jobs of the Apache user:

$output = shell_ex         


        

Answer 1

The easiest way is to use the shell_exec command to execute a bash script, passing in the values as parameters. From there, you can manipulate crontabs like you would in any other non-interactive script, and also ensure that you have the correct permissions by using sudo etc.

See this, Crontab without crontab -e, for more info.
