I have finished my premium project finally, but it still needs last enhancements, I want to sell it and give premium keys so only the key holders can run the version.

I have already made a basic system for such thing; http://brutallyviralwpplugin.com/check/form.html

but I am sure the code can be ripped off and the version is going to work without it... so I need to make it harder for crackers to do so,at least without help from Zend Guard or Ion Cube (ugh I just hate them)

PHP is an open source, and is compiled at run-time. Therefore, anyone who knows PHP can remove any licensing code you put in. The only way to provide effective licensing/IP protection for PHP code is with Zend Guard/Ioncube et al.

In short, what you are asking for cannot be done. Full stop.

yes I know that, even computer codes can be cracked after disassembling it, but there must be easy way like what invisionpower and vbulletin uses to prevent some users from cracking it... –  SAFAD Sep 30 '11 at 9:18
You've never seen a cracked ('nulled') version of vB or IPB? As DaveRandom said, what you're asking for cannot be done (even with Zend Guard and whatnot in my opinion). –  Corbin Sep 30 '11 at 9:27
i've seen it, but i'm sure it already blocked many crackers from using it ... –  SAFAD Sep 30 '11 at 9:37
