Summary: Cannot open file descriptor streams
Status: Duplicate
Type: Bug
Package: Filesystem function related
Operating System: Linux
PHP Version: 5.3.3

New Comment:
The problem with "php://fd/3" instead of "/dev/fd/3" is that when I use
anonymous fifos in bash like this:
php -r 'var_dump($argv);' <(echo "hello")
then the output is as follows:
array(2) {
[0]=>
string(1) "-"
[1]=>
string(10) "/dev/fd/63"
}
which means that if you have an existing PHP program which accepts filenames,
you have to add extra "if" to it, with special case just to handle /dev/fd/63
->
php://fd/3 conversion. I think that this adds extra complexity for the
developer
in a place where Linux tried hard to eliminate it.

5.3.4 is in the final stages of the release process, so it will not be
possible. Maybe 5.3.5, if the release manager agrees with the inclusion.

This works like a charm. I much prefer the php://fd/ syntax to fixing the
/dev/fd symlink trickery, anyway. The patch also applies cleanly against the
5.3 branch. Will this be in 5.3.4?

I've attached a patch (against trunk) that allows duping+open arbitrary file
descriptor. /dev/fd doesn't seem like a good option because it's not portable.
Example:
<?php
$f = fopen("php://fd/1", "w");
fwrite($f, "test");
Can you see if this is enough?
Thanks.
