From what I understand, FPM isn't currently available for the Windows port of 
PHP due to it's dependency on libevent.  I'm logging this feature request as 
having FPM available on Windows would be a great boost, especially with the 
recent release of Apache 2.4, containing a new mod_proxy_fcgi module for its 

If libevent doesn't provide enough cross-platform support to be suitable for the 
task, perhaps other libraries could be considered to power FPM.  For example, 
Microsoft have worked with nodejs to help produce "libuv" which they call a 
"BSD-licensed, minimal, high-performance, cross-platform networking library".

It appears to put a lot of effort into Windows networking and then taking 
advantage of the libev and libeio libraries for supporting other operating 

Some developers have already started trying to make use of libuv in PHP...

Test script:
Unable to test, no FPM support exists for Windows.

it is not due to libevent, libevent (or similar libs, or using native APIs) are 
available on Windows.

The problem is the core design of FPM, which is based on fork(), which is not 
available and can't be emulated in a good way on windows.
