Newbie asks about accessing COM from C...

I've got a series of COM objects that I thought I'd be able to access
through PHP, but it looks like I'll need to write a C "PHP Extension" to do
the work and pass data to the PHP scripts. I understand how to write an
extension, I'm well acquainted with working with developing DLLs in C.

The part I don't know is the syntax of using COM and I'm pretty rusty with
C++. I have an interface diagram and know the methods I need to call. But
I have some IDL/TLB files that I'm not sure how to use. I added the IDL
files to a quick project that I was toying with and I can browse them in the
Class View...

1) Is there a baby-step guide for instantiating these objects (I don't know
a CLSID from an IID - I'm not even sure where to look these up)?

2) The other question is how to integrate a blob of C++ code into a C DLL.
The C file is pretty heavily entrenched in "C-ville", there are a ton of
macros and things I don't want to think about converting. Plus I need to
make sure that the DLL is loadable/callable by the server. So unless I code
the COM interface piece in C, I'll have to mix the languages.


Thanks for any help,
