Protecting php scripts

Anon

Hi,

If I create a product using php, how can I stop the
scripts from being copied and reused on another
system ?

ta,

Just keep people from hacking your server: PHP is server-side,
so the only thing the client browser sees is the html that
is generated by your PHP scripts, not the scripts themselves.

I believe implementing this would slow the script, and it won't worth. There are other ways of encoding your script, like renaming all your variables to boring strings.

I think both responders misunderstood your question.

Did you mean "how do I stop someone who buys my PHP script from copying the source code and selling it"?

Or did you mean how do I stop a visitor to a PHP backed website from reading my source code?

If the first, that's a good question, and you can't. Zend are supposed to be working on a compiler, though.

If the second, then as long as your web server is properly configured then visitors can't read your code. One tip, rename all included files to file.inc.php or else get your server to send *.inc files with PHP.

The user can't, anyway know the included(required) script filenames. The problem is, I guess, how to protect them agains anyone, including ISPs, PHP hosted WebMasters, anyone who can see the php files. This is free software.
