Can I change current directory to parent directory using PHP DIR constant?

Question

I am using PHP magic constant to move uploaded file to a new location, and the upload handler file location is inside "_inc" file inside the main application folder like this:

"path/tasksapp/_inc/upload_handelr.php"

So; when I use __DIR__ I get the path where the upload hander is exist:

"path/tasksapp/_inc/"

While the new location for uploaded file should be:

"path/tasksapp/uploads"

Is there's any option or attribute I can use with __DIR__ constant so I can change current directory to parent directory:

change:

"path/tasksapp/_inc/"

to be:

"path/tasksapp/"

Do you have a main file in `path/tasksapp/` that includes/requires `upload_handler.php`??? — AbraCadaver, Sep 29 '15 at 20:47
It would be `__DIR__ . '/../uploads/'`. But might I suggest using a singleton to store this configuration property (or something similar) so that your code doesn't care (or even know!) where it's located and how that is relative to files that it needs to move. — Charlie Schliesser, Sep 29 '15 at 20:55
@AbraCadaver it's not working, it gives "/tasksapp/_inc/../uploads/" ! — CairoCoder, Sep 29 '15 at 21:00

I recommend dirname(__DIR__):

it's portable (works on Windows where a/b/../c is not allowed)
it's readable

Inside `upload_handelr.php` something like `$dir=dirname(__DIR__)` would create a variable pointing to the upload directory. Append the filename use `move_uploaded_file()` – Eugen Rieck Sep 29 '15 at 21:03
