View as plain text  
I think in the software world pretty much anything can be done,
not 100% to the specs but using the 'for all practical purposes'
criteria.
it's a matter of the cost but the PHP + mysql combination
certainly can't protect the datamodel because most of it
can be hacked from the data files themselves. So first thing
the OP needs is a custom mysql code to make it difficult
(not impossible). One thing that comes to mind
is to disable all forms of caching to avoid getting much from the 
memory dumps.
If he's willing to do this than switching from PHP to a binary 
executable
will be a breeze, or the PHP script will use callouts to proprietary
interface of the customized mysql.
I think it would be safe to claim that all data in the world that is 
worth this kind
of investment is already available either free or for a modest fee,
think Linux or mysql source code or any good book you can by for a few 
dollars.
Bigger products often have a funny and not at all intentional builtin 
mechanism
against pirating where it's very hard to install and use the software 
unless
you also buy a support contract.

Thanks,
Michael

I think the OP is more concerned with protecting his datamodel, and 
this
cannot be done in my opinion.
