filename argument may be a directory name allowing you to check
if a directory is writeable.

that the web server runs as (often 'nobody'). Safe mode
limitations are not taken into account.
The results of this function are cached. See
clearstatcache() for more details.
This function will not work on remote files; the file to
be examined must be accessible via the server's filesystem.
See also is_readable().
