I'm trying to delete specific cron job with my PHP script. First of all I'm trying to get current cron jobs using shell_exec:
shell_exec('crontab -l');
When this script executing from webbrowser shell_exec returns all current cron jobs. But when this script executing from cron job shell_exec returns empty string. Why?
On another webhosting this works fine, but here I have this issue. I tried to find the reason or solution, tried different ways but didn't found any working solution.
