How can you ensure that the correct user permissions are set for PHP scripts executed via cronjobs?

When executing PHP scripts via cronjobs, it's important to ensure that the correct user permissions are set to avoid any security risks or issues with file access. One way to do this is by specifying the user and group that the cronjob should run as in the crontab configuration. This can be done by using the `sudo -u` command in the cronjob command to run the PHP script as a specific user.
