May I request for some function?

Dear php group, I am a developer of Visual Basic.I am writing a simple web server.I want to add php support.But by the "shell" function of Visual Basic,it is too slow to execute through php.exe or \cli\php.exe,and it causes some security problems too! So,is there any better methods? I think the developing group can write a somple .dll file.There is only a function that I can pass the varible to the .dll.And after the execution of php.The results send back to the Visual Basic program by the same varible. I think it is not so diifficult to write. I think it can help a lot of developers who do not know C++ very much. Please reply. Thanks for your attention.
