Restart Apache using Cron job in php

Sometimes we need to restart apache from our scripts automatically. Other than root user privileges, other users need to use sudo keyword to restart apache. But it needs password for sudo command. We can change sudo permissions and set options with the /etc/sudoers flie. Edit the file with the following command:
sudo visudo 

php scripts are run with www-data user previleges. We can get the current user info with the command:
whoami
So, we need set options in the /etc/sudoers flie for user www-data. Set the following:
www-data ALL=NOPASSWD
So, sudo will not prompt for password while running the script.
Use exec functions to execute your command through php.
