mkdir and is_dir length limit?

Question

I created a folder through Windows Explorer, but is_dir returns FALSE.

A path that fails:

ficheiros/dinamicos/multimedia/imagem/areas/galerias/actividades/professores/iii-xxxxxxxx-xxxxxxxx-xx-xxxxxxxxxxx-xxx-xxxxxxxx-abcdefg/__fmhidden__681d75e470b4fd52f7d3b468b8ce7b5b/__fmhidden__b14a7b8059d9c055954c92674ce60032

This one doesn't fail:

ficheiros/dinamicos/multimedia/imagem/areas/galerias/actividades/professores/iii-xxxxxxxx-xxxxxxxx-xx-xxxxxxxxxxx-xxx-xxxxxxxx-a/__fmhidden__681d75e470b4fd52f7d3b468b8ce7b5b/__fmhidden__b14a7b8059d9c055954c92674ce60032

My code used to work flawlessly for months. After debugging it, I found that the problem was with mkdir/is_dir. The strange part is that it only happens when the path length was bigger than 218 characters (247 as absolute).

Is there any limit to the path length for is_dir and mkdir (in Windows environments)?

The file name limit is completely up to the OS (Windows, Mac) etc. — Rottingham, Sep 13 '13 at 16:27
Could you submit the file path you are using? Are you looking at a network drive or a local drive? — Rottingham, Sep 13 '13 at 16:31
It's a local drive, I'll mask the path but keep the length... — MJC, Sep 13 '13 at 16:53
@MarioCesar, In windows max length of folder path is "247 characters + ``". See http://stackoverflow.com/a/15971467/632951 — Pacerier, Aug 18 '15 at 06:14

In Windows the character limit of file paths is 260 (with some exceptions) so the PHP mk_dir and is_dir functions may not work as you expect.

thank you. That should be the issue. It isn't that problematic since it will only be deployed in unix systems – MJC Sep 13 '13 at 20:39
