Bug description:  CLI PHP: STDIN/OUT/ERR are not the good fd's

Description:
------------
Hello.



I'm trying to run a php script from xinetd (Fedora Linux). I need to close
stdin, stdout & stderr since I want to close the socket established with
the caller process (I have a long processing to do locally, I need to
release a remote resource & closing the connection is the only way I can
do it).



I've tried :



fclose(STDIN); fclose(STDOUT); fclose(STDERR);



It does not work, the socket is still up & running.



When I run strace(1), I see that I'm closing fds 4, 5 & 6 (fd 3 is the fd
of the script being read) and not fd 0, 1 & 2.



It seems that CLI PHP calls dup(2) to get duplicates of fd 0, 1 & 2 and so
these 3 fds are totally unreachable from the script itself.



I'm not used to php source code, but I think that the problem comes from
getting constants STDIN, STDOUT & STDERR thru filter code generation used
by "php://stdin" etc. and no provision is done for the first calls:

a dup(2) is automatically used.



So constants STDIN, STDOUT & STDERR are not pointing to the correct fd's,
but dup's.
