Multi Company Site

[rleitman]

I have a pure php site where you need to login to see the info (e.g. its forum like system) , the system has users and groups with permissions. However, I want this system to serve different companies, so each company access the site and see only its data. The common way I did it is replicating the whole code and DB and just install it several times on my sub domains. I wonder if there is a best practice so I can install it only once somehow and make sure each company see only its stuff and can admin it.

use control fields, like 'parent','company', or 'instance', to filter results. that way you've got one table for all users for example, but each user has a 'parent' or 'company', and a user list will only show the ones related. make sense?
