PHP Manual: Copy specified messages to a mailbox

bool imap_mail_copy(
    IMAP\Connection $imap,
    string $message_nums,
    string $mailbox,
    int $flags = 0
)

Copies mail messages specified by message_nums to specified mailbox.

imap

An IMAP\Connection instance.

message_nums

message_nums is a range not just message numbers (as described in » RFC2060).

mailbox

The mailbox name, see imap_open for more information

Warning

Passing untrusted data to this parameter is insecure, unless imap.enable_insecure_rsh is disabled.

flags

flags is a bitmask of one or more of

CP_UID - the sequence numbers contain UIDS
CP_MOVE - Delete the messages from the current mailbox after copying. If this flag is set, the function behaves identically to imap_mail_move.

Returns true on success or false on failure.

Version	Description
