It is not about making sense or not. It is about backward compability and how
they
actually behave from a file system point of view.
Think of junction like hard links. You can't see hard link with is_link, no
matter
the platform.

Mmm, if it walks like a duck and quacks like a duck...
For all scenarios I can figure (backups, deploying code using symlinks),
treating a junction as a symlink makes more sense than not doing it.
Right now the only way to tell if a folder is actually a "real one" or not is
to use the array_diff trick I put in the test script. It looks hackish,
cumbersome, and why should lstat() treat a junction differently than is_link()
anyway?)
It is true that windows versions starting with Vista do create symlinks by
default, but tools like "Link Shell Extension" or the venerable sysinternals
junction.exe still allow one to create Junctions.

Junctions are not symlinks, the result is correct. Also the
junctions pointing to a directory may work. I remember
some windows version specific changes here, where it
ended as symlink or junction (recent always do it as
symlonk afair)

Description:
------------
is_link seems to return false for junction points which show up as <JUNCTION>
when using the DIR command.
It seems to work for junctions which show up as <SYMLINKD> when using the DIR
command.
tested on php 5.3.27 and 5.4.14 (32 bit of course)
Test script:
---------------
<?php
$paths = array(
"linksource",
"linktarget",
"linktarget2"
);
foreach ( $paths as $path )
{
echo "----\n $path\n";
var_dump( is_link( $path ) );
var_dump( is_dir( $path ) );
var_dump( array_diff( stat($path), lstat($path) ) );
}
Expected result:
----------------
results of DIR command:
07/09/2013 15:59 <DIR> linksource
07/09/2013 19:11 <JUNCTION> linktarget [D:\htdocs\linksource]
18/09/2013 14:30 <SYMLINKD> linktarget2 [linksource]
Actual result:
--------------
D:\htdocs>php linktest.php
