Fire Rule Set programmically

You'll probably have to use something like

if you want to fire the rule set with PHP. To give a 30 days' notice I would suggest using Rules Scheduler.

Heh.

Another way of doing it is using rules_evaluate_rule_set() or possibly rules_invoke_rule_set(). I don't really know how to use them (and I have never tried calling a rule set in code), but you can proabaly/hopefully find what you need on the following pages:

http://drupalcontrib.org/api/function/rules_evaluate_rule_set/6
http://drupalcontrib.org/api/function/rules_invoke_rule_set/6

(I was a little confused by the second argument in rules_evalute_rule_set. And the third and the fourth one.)
If you find an easy way to describe how to call rule sets from PHP, a line or two in this thread would be appreciated.

Good luck!
