server wide cron job

I need to run some cron jobs on PHP scripts that should have server-wide access, what would be the best location to store them and how to set them up so that they don't have any permissions issues?

 

You can set them up as root by running

Code:

crontab -e

 

thank you Falko

I need to test the script first, is there a way to execute the PHP script from http with root privileges?

would something like that work if I add it to /etc/sudoers

Code:

web1 ALL=(ALL) NOPASSWD: /usr/bin/php -f /var/www/clients/client1/web/myscript.php

?
