@ Joozey:
I should have mentioned it more clear indeed, your DLL will lead to your database
Thus users need to wait until you changed it towards the final version.
@ William:
If you set up your own private MySQL database (and not shared by any other users), then there is really no problem. The problem occurs (as D3D mentioned) once you start letting other users connect towards your database. PHP is very easy to learn since that was the general intention of the developers of PHP but it brings one problem
Due to the fact that it is that easy, a shared database makes the php scripts visible so other users can attempt to change it (like D3D mentioned as well ^^)
Keep to the basics, make it private to say it simple
