note 18436 added to function.is-dir

Under (at least) php 4.0.6, is_dir returns false if the parent directory is unreadable, for example /home/user is mode 750, owned by user.user /home/user/stuff is mode 777, same owner is_dir("/home/user") returns false but so does is_dir("/home/user/stuff"). It seems to me that php attempts a tree traversal instead of directly accessing the directory in question. -- http://www.php.net/manual/en/function.is-dir.php http://master.php.net/manage/user-notes.php?action=edit+18436 http://master.php.net/manage/user-notes.php?action=delete+18436 http://master.php.net/manage/user-notes.php?action=reject+18436
