Database access from an external page

[paladin]

Hey guys im toying with writing a module that uses pay pal ipn to make some changes to database tables.

Using an old script i wrote i can make the changes but this requires the raw details concerning passwords and so on being stored in free text....this script is only for testing.

I want to know if there's a way to access the CMSMS getDB() function from a single php page that is not a class or included in the module main code.

If someone could help me out that would be great i have been stuck on it for a while. I hope its just me being tired
