[development] creating a file - path problems

[andrew morton]

It's a bit of a pain to learn but you'll save yourself some headaches
by using Drupal's file functions in includes/file.inc for doing path
handling. If you're trying to create a file in Drupal's files
directory use:
  file_create_path('the/desired/filename.ext');
which give you a path relative to Drupal's root. If you need the full
path from the server root you'll need to use PHP's realpath() which
only works with existing files so you'll need to use:
  realpath(file_directory_path()) . 'the/desired/filename.ext';
Once you get some data saved in there you can use file_create_url() to
get a URL for the file that you can send out to visitors so they can
download the file.
