Status: Feedback
Bug Type: Directory function related
Operating System: win32 only - Windows Server 2003
PHP Version: 5.3.0
Assigned To: pajoye
New Comment:
Using junctions: is_file and file_exists are giving incorrect behavior
(false on files). is_dir as well, false on directories in the junction
and the junction itself.
The same functions are working well with symlinks.
If you need testing for this, you have mail.

Using is_dir and is_file or file_exists and the cases you described,
does it work? (I don't think the filetype issue is related to what we
discuss here).

I was able replicate shoresofnowhere's behavior using windows 7...
I created a junction to a folder on another drive; running is_file() on
a file inside that junction returned false, as did is_dir(). Curious to
see what php thought it was looking at, I tested filetype(), which threw
an error.
I then tested symlinks in the same manner, and got good behavior.
Symlinks seem to be a good workaround for this issue.
Test log follows:
C:\mnt\test>mklink /J junction_otherDrive f:\downloads
Junction created for junction_otherDrive <<===>> f:\downloads
C:\mnt\test>mklink /D symlink_otherDrive f:\downloads
symbolic link created for symlink_otherDrive <<===>> f:\downloads

Ignore my last two comments, it works perfectly using what you
describe. I was testing it from another VM where this junction did not
exist.
I added a include 'dir3/two.php' to one.php, two.php being a simple
echo "two.php"
The output:
C:\test>\php53\debug_ts\php.exe -n one.php
two.php
bool(true)
C:\test>junction dir3
....
C:\test\dir3: JUNCTION
Substitute Name: e:\test
C:\test>dir dir3

ok, I can reproduce it now. I will come back as soon as I have a fix.
