I've read a few threads foudn via the search on this topic, but I was just wondering if anyone had any of the following:

- Tips to handle serial numbers/licenses within the scripts
- Any websites/articles that mention this
- Tips on GENERATING the serial numbers???

Of course, seeing as how PHP is open source, it is very hard to do something like implement a checker, because those lines could just be removed. If anyone could please provide any details on this, it would be greatly appreciated!!!

well with php you could use like ioncube and just encode the php :)

I really don't want to encode the code... Really all I've heard about this is bad things... and I want users to be able to modify the code... add their own things.

I was thinking about adding a license to one of my programs. Could always require people to enter a license code with their program unique to their website ip or url. Of course could be reverse engineered if they understand the code well enough but I guess its a morality issue, any program can be cracked really...

I never used license #s until now, however, I will be giving all current (and new) customers an order id, and this will be required for upgrades and support.

Just brought up a question myself... which "name" do you think???
-Serial #
-License key (or something to that effect)
-Order ID
-Something else?

Would customer ID not be another?

yes, actually thought of customer id after posting that :) hehe.. I think I will go with customer ID too...
