Hi
I have found this in PHP manual ..
1. I have built a DLL to calculate something. Is there any way to run this DLL under PHP ?
If this is a simple DLL there is no way yet to run it from PHP. If the DLL contains a COM server you may be able to access it if it implements the IDispatch interface.
So first you need to answer this question...
Than read this document in PHP manual..
72. PHP and COM
Hope that will help
