How can i encrypt my php source code, using any free script (unlike IONCube).?

I just want basic protection, just a hard to read program. Maybe any software which converts a simple to read program to a really hard one?

PHP codes were already parsed by the browser (IIS and Apache), so you don't need to encrypt it because, the return code for the users (to view your page) were converted to HTML code only..you don't need it.





Edit:


just try to give the idea (not the code)..

Reply:People can only see the output of the php code in their browser (html)
Reply:You can use Zend Guard which encrypts your code. The only downside is that you will need to have Zend installed on the server. But, I think most major hosting companies have Zend installed.

OR, if you are crazy enough, replace all your variables with random strings and remove ALL whitespace. It won't stop someone from really taking your code, but it will prevent most or at least some "kiddie hackers" from hacking your code.
