note 48613 added to function.is-dir

For example i have 4 folders in /home directory on unix platform (a,b,c,d) and php5. The script: <?php $files=scandir("/home"); foreach ($files as $file) { if (is_dir($file)) { echo "dir: $file"; } } ?> I have strange thing that function is_dir not always shows every dirs as it is dir. In my example script is_dir returned only "c" as dir and the rest (a,b,d) as file. ---- Manual Page -- http://www.php.net/manual/en/function.is-dir.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48613 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48613&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48613&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48613&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48613&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48613&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48613&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48613&report=yes Search -- http://master.php.net/manage/user-notes.php
