For this is there any tool....
i searched in the internet i found zend guard.
next one i got some PADL (PHP Application Distribution License)
but i am not clearing about above one pls anybody knows reply for this
You must first obfuscate/encode (or both) your code to do this.
For it to "expire" there has to be some registration date to install your software. (See how PHPBB does it). Maybe automatically set it in DB, but HiDe it. (ie call it something other than "expiration date", call it ....er "print functoinality" and make it date in Unix format (bunch of integers), you get the point.
You could also have the software report back to your server (if its always connected to the internet) and build an API that checks the status of the subscription. XML?
It is very difficult to really protect PHP code. But once you obfuscate it and encoded it, you'll be one step closer to security. All you have to do is just program a self-expire in the "demo" version of the software.
Good luck,
Dan
