Would there be any way to adjust cron tasks over a PHP web interface? I was thinking I could just use shell_exec() commands but it runs into a snag when crontab -e launches a text editor. If cron isn't the thing to use for this job, then I will gladly take other suggestions compatible with Raspberry Pi. My end goal is just to be able to adjust the time that a program is run over a webpage.

I think most web-edited crons insert the specific information into a database, then use an actual cron to run a script that checks those entries. – aynber May 03 '18 at 18:27

Mine does `exec('echo '.escapeshellarg($newcrontab).' | crontab - 2>&1',$ret,$code);` – Niet the Dark Absol May 03 '18 at 19:02
