PHP Licensing system

[Hypertext]

Are we talking pure PHP?

Because if so, it's near impossible to stop somebody nullifying/unlicensing software.

Ok, Change of Plans then.
Any ideas on a site I should make?

Doesn't matter how complicated it is, I'm just wanting a sweet idea.
Thanks

It's possible to make it not able to be removed, but it's not possible to let them figure out how it works

My personal way would be to have some core functionality that calls method, off your own server, for instance an API type thing, whereas you only give out the client.

The thing is that it's actually really quite difficult to make a catch all licensing system for release. The main reason is that it requires the person to know the licensing script well before they can integrate is effectively and securely. If they don't know the system, then they'll probably leave a hole and they will have wasted their time. For this reason, in my opinion is it best to code a customized license system for each application, preferably coded by the writer of the software it's for.

When I have made scripts in the past, I have tried to avoid licensing and obfusucation because it stifles the creativity of users. For example, if you want to allow plugin development, people need to see the code really. In the past I have thought of having one protected file with just licensing functions and a core function, but the problem is that if some really wanted to they could rewrite the core functions to get around it.

For this reason, my applications have tended to have open sources, and just because I'm kind

That's what I just said.. when the class is constructed, have it automatically call a check function, which then returns the output on whether or not it should continue.
