php / post / include between two servers

[Humpty]

G'day again all.

 

I have something that I am trying to sort out.

 

Background:

I am making an ISP front end billing system.  At this stage each ISP will have a sperate server (linux jail session). I have all the code i need working all on one server with the one MySQL and multi databases and tables.

 

The issue I am having is now that the boss wants to put some ISPs into a different jail session (so that they can tinker with the code) there are parts of the code I want them NOT to tinker with.

 

Example:

Lodging an ADSL fault: Although they have all the DSL details available to them I need it to be written, along with additional information and notes provided by them into a seperate database on a seperate server (jail session).

 

I need to hide all files / code / usernames and passwords, tablenames etc that are needed for this one process but still give them the ability to use it.  (so it will work for them, but they won't have the code to view other ISPs faults and etc.

 

Any ideas on how BEST to do this?

 

Thanks in advance, if it's not clear ask the question and i'll answer it.

Edit:

We have full access to the server(s), I am just not sure on the best way to tackle the situation.

 

Using a username and password that only has insert permissions is no good because we also need them to view the feedback which means we also need query permissions but then there is nothing from stopping them from accessing all the othe ISPs info in that faults table if they have that permission.
