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 :)


Florian
