function is_dir

Hello, same comments using PHP function 'is_dir' under Windows NT/XP using IIS, PHP as CGI: Path: D:/folder1/folder2/folder3 Example 1: NTFS rights of folder2: admins, system: Full, guests: READ NTFS rights of folder3: unimportant (even, if nobody has a right for this folder) is_dir("D:/folder1/folder2/folder3") --> TRUE --- Example 2: NTFS rights of folder2: admins, system: Full (Note: Guests are removed) NTFS rights of folder3: Everyone: Full is_dir("D:/folder1/folder2/folder3") --> FALSE --- It seems that next directory above must have the appropriate NTFS rights to get the right result of 'is_dir()'. Also it seems that this 'rule' ist not valid for the root directory of a drive: Example 3: NTFS rights of Drive D: admin, system: Full is_dir("D:") --> TRUE --- It seems that the NT user right 'Bypass traverse checking' has no influence of this behaviour. Mit freundlichen Grüßen / best regards Markus Weber _________________________________________________
