protecting copyright line in an open soruce php code

[khr2003]

hi
I guess the title says it all. Is there any way that I can disable the users of my open source php code from removing the copyright line?

Hide it in a sea of confusing code... hehe

But the only way I can think of is to scare them off with legal terms in your license or readme.txt file... because I think that as long as they can understand the code, they can probably remove it. (sorry it didn't help that much)

thanks for replying

I was wondering if there is a way to encrypt part of the code (and not the whole code) so it becomes ambiguous or non-removable.

As of the legal rights it would not be useful that much since the code is downloaded mostly in the middle east area (which does not have strong legal system).

I just googled this:

But basically what it does is just 'muck up' or confuse the code to make it hard for others to edit the source. =( The download is just a trial version.
