|
|
@discussion NOTE: as of Oct 17, 2001, the $part_num used here is not always
|
|
the same as the part number used for official imap servers. But because this same
|
|
class produced the fetchstructure, and provided it to the client, and that client
|
|
will again use this class to get that part, the part number is consistant internally
|
|
and is MUCH easier to implement in the fetchbody code. However, in the future, the
|
|
part numbering logic in fetchbody will be coded to exactly match what an official imap
|
|
server would expect. In the msg_msg class I refer to this "inexact" part number
|
|
as "mime number dumb" as it is based only on the part's position in the
|
|
fetchstructure array, before the processing to convert to official imap part
|
|
number, which msg_msg class refers to as "mime number smart", which
|
|
is used to access mime parts when using PHP's builtin IMAP module.
