Answer 1

you can use: is_writable

eg:

if(is_writable('/path/to/your/dir/'))
{

}

from PHP Manual:

is_writable

Returns TRUE if the filename exists and is writable. The filename argument may be a directory name allowing you to check if a directory is writable.

Keep in mind that PHP may be accessing the file as the user id that the web server runs as (often 'nobody'). Safe mode limitations are not taken into account.
