imap_fetchheader — Returns header for a message

imap_fetchheader(IMAP\Connection $imap, int $message_num, int $flags = 0): string|false

flags

The possible flags are:

FT_UID - The message_num 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)

Returns the header of the specified message as a text string, ou false em caso de falha.
