I have an interesting question. Is it possible to call a dll on the client machine from the server? I haven't found anything in my searches. I have been also wondering if I would have to write a custom extension for php to do this?
My main goal is to call a dll in the C:\Windows\System32 directory on the client. I have seen a Java application do what I want but I would have to buy a $800 security certificate so that the user could run the app on their machine. Maybe I need to look into a COM DLL or Webservice. Or even write a C/C++ app that connects to the server. I would like to know first if it can be done in PHP.
