imap_fetchheader

(PHP 3>= 3.0.3, PHP 4 , PHP 5)

imap_fetchheader -- Returns header for a message

Description

string imap_fetchheader ( resource imap_stream, int msgno [, int options])

This function causes a fetch of the complete, unfiltered RFC2822 format header of the specified message as a text string and returns that text string.

The options are:

  • FT_UID - The msgno argument is a UID

  • FT_INTERNAL - The return string is in "internal" format, without any attempt to canonicalize to CRLF newlines

  • FT_PREFETCHTEXT - The RFC822.TEXT should be pre-fetched at the same time. This avoids an extra RTT on an IMAP connection if a full message text is desired (e.g. in a "save to local file" operation)
