I got around this by replacing the "." with my local address
"\\\\.\\pipe\\pipename"
"\\\\127.0.0.1\\pipe\\pipename"

But it's just a matter of not corrupting the filepath. This is a bug in
a way, as, for the same reason, the function cannot handle
"\\.\C:\filename.ext", which is a valid Win32 path.

Indeed, Wez and I both have our eyes on named pipe support. With luck
it'll show up in 5.1, in any case it should be a simple backport to make
it available to 5.0 via a PECL extension.

Let's make this a feature request as it's currently not meant to work.

Description:
------------
fopen() can't handle path names like "\\.\pipe\pipename" because the
internal function virtual_file_ex() see the ".\" part, thinks that it
means current directory, and promptly removes it.
The manual doesn't mention named pipes but I think this is worth fixing
as it will give PHP Win32 a robust interprocess communication mechanism
that's fairly easy to implement. The fix is easy enough. Insert the
following at line 413 in tsrm_virtual_cwd.c, right after the else if
(!IS_DIRECTORY_CURRENT(ptr, ptr_length)) loop:
#ifdef TSRM_WIN32
/* '.' should be retained if the first two
chars are '\' as it
stands for local machine
done mainly for paths to NT named pipes
(\\.\pipe\pipename) */
} else if(state->cwd_length == 2 && state->cwd[0] ==
'\\' &&
state->cwd[1] == '\\') {
state->cwd = (char *) realloc(state->cwd,
state->cwd_length+ptr_length+1);
memcpy(&state->cwd[state->cwd_length], ptr,
ptr_length+1);
state->cwd_length += ptr_length;
#endif
}
Reproduce code:
---------------
Set break point at line 1975 in streams.c
fd = open(realpath, open_flags, 0666);
then run <? readfile('\\\\.\\pipe\\pipename'); ?>. Inspect realpath.
Expected result:
----------------
realpath => \\.\pipe\pipename
Actual result:
--------------
realpath => \\pipe\pipename
