Hi,

i recently wrote small function that allows the creation of a php-socket 
by directly giving the fd#

this is very useful under linux/unix environments for Ipc.
For example:
getting forked by a webserver as fastcgi / scgi .., the webserver gives 
an acceptable socket as fd#0 to the process..

I submitted the patch about 3 weeks ago @ pecl-dev list in the fdpass 
extension topic.

It would be nice to see such function in dist php :)

I can commit this, but a few changes are required first:

* This doesn't work on Windows, so it should be ifdef'd out on that  
platform.
* The family can be detected
* The blocking behavior should be queried, not hardcoded to 1
* This patch is not up-to-date with trunk/5.4 (see php_create_socket)

For the two last points, see the implementation of socket_import_stream in  
http://lxr.php.net/opengrok/xref/PHP_TRUNK/ext/sockets/sockets.c#2434
It would be a good idea to do some refactoring and share code between the  
two functions.

* (remark) "For IPC", the vast majority of use cases would be already  
covered by php://fd; you would this this only for socket specific  
functionality.
