# Method MIME.Message()->is_partial()

Method is_partial

  `array(string|int) is_partial()`

Description

  If this message is a part of a fragmented message (i.e. has a Content-Type of `message/partial`), an array with three elements is returned.

  The first element is an identifier string. This string should be used to group this message with the other fragments of the message (which will have the same id string).

  The second element is the sequence number of this fragment. The first part will have number 1, the next number 2 etc.

  The third element of the array is either the total number of fragments that the original message has been split into, or 0 of this information is not available.

  If this method is called in a message that is not a part of a fragmented message, it will return 0.
