How do I save form data to a file, as with perl cgi.pm query->save(FILE) ?

I would use the serialize() and unserialize() functions.  First, get a
serialized string to write to your file:
>>> $string = serialize ($_REQUEST);
$_REQUEST has all of $_POST, $_GET, and $_COOKIE
Next, take $string and write it to a file (read the manual).
To restore the information, read the data from the file into a string
and then unserialize:
>>> $restored_REQUEST = unserialize ($string);
I have used this to successfully store an associative array in a file
and call it back up from another program.
