I have a Windows hosting account that as well as giving out really nice ammounts of space for my $12 (about £6) gives me:

ASP.NET
ASP
Code Behind
MS-SQL/MY-SQL etc

and

PHP (v4 I think)

Now this is where it gets interesting.

I have a bunch of code that I think of as a base or core system written in classic ASP. It provides include files with Class objects written in VBscript for ASP and a few general functions that go through the more complicated bits of database and get you the value you require.

The design is such that one should be able to create a wrapper for other apps and include them in the authentication etc and make them part of the system with minimal changes.

My question is could I do that with a PHP module and if so could I use the Class objects and can I call the functions?
