New Comment:
Wrote this and my Win 8.1 with PHPs 5.4.29, 5.5.13, 5.6.11 don't reproduce: is_file says no,
is_dir and is_link say yes.
Note that you will probably need an elevated command prompt to run mklink.
<?php
$tempnam = tempnam(sys_get_temp_dir(), "php");
unlink($tempnam); // tempnam created a file
// expecting to see "symbolic link created for %s <<===>> C:\"
// - /d to create a directory symlink
// - /j to create a junction
passthru("mklink /d " . escapeshellarg($tempnam) . " C:\\");
clearstatcache();
if (file_exists($tempnam)) {
echo "Created directory {$tempnam}\n";
echo "- is_file: ", (is_file($tempnam) ? "yes" : "no"),
"\n";
echo "- is_dir: ", (is_dir($tempnam) ? "yes" : "no"),
"\n";
echo "- is_link: ", (is_link($tempnam) ? "yes" : "no"),
"\n";
rmdir($tempnam) or printf("Failed to remove directory\n");
} else {
echo "Directory {$tempnam} does not exist\n";
}
?>

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Neighter is_link nor DirectoryIterator->isLink are not distinguish symlinks created with os
command mklink. Os is showing them:

My env is Win 7 x64, WAMP (Apache 2.4.9, PHP 5.5.12 Thread Safe).
Test script:
---------------
if ($handle = opendir($dir)) {
echo "Directory handle: $handle\n";
echo "Entries:\n";
while (false !== ($entry = readdir($handle))) {
if (is_link($dir . $entry)) {
$strTarget = readlink($entry);
echo '>>LINK<<: ' . $entry . ' => ' . $strTarget .
"\n";
}
elseif (is_file($dir . $entry)) {
echo 'File: ' . $entry . "\n";
}
elseif (is_dir($dir . $entry)) {
echo 'Dir: ' . $entry . "\n";
}
else {
echo "? - $entry\n";
}
}
closedir($handle);
}
Expected result:
----------------
both of those methods should return true
Actual result:
--------------
both of those methods should return false
