I'm using xampp.
I search and it looks like for php 4.x, there was an extension called php_w32api.dll which seems to have vanished for php 5.x. Nevertheless, it's still in the documentation on php.net but marked as experimental.
Some suggested to use win32std in pecl instead, but that just wraps some function of the win32 api, but doesn't allow me do call my own dll functions. :/
There is ffi, but the link on the pecl site is dead and it seems like development has stopped in 2004.
Any idea how to do this without writing my own php extension?
Best regards Marc
