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 :)
