   The <function>fdf_open</function> function opens
   a file with form data. This file must contain the data as returned
   from a PDF form or created using <function>fdf_create</function> and 
   <function>fdf_save</function>. 
  </para>
  <para>
   You can process the results of a PDF form POST request by writing 
   the data received in <varname>$HTTP_FDF_DATA</varname> to a file
   and open it using <function>fdf_open</function>. Starting with PHP 4.3
   you can also use <function>fdf_open_string</function> which handles temporary
   file creation and cleanup for you.
