I recently finished my PHP app and i would like to know if there's a possibility to have a kind of trial period. So that when that period is reached an error appears on the screen.
Thanks for your time and answers. I most appreciate them.
You can encrypt your sources using Zend Encoder or Ioncube, or obfuscate them.
But the fact is that everything from above can be patched. So if target user is experienced enough - they could remove your trial period checks.
