在 PHP IMAP 中标记电子邮件未读

Question

Are there any PHP IMAP functions which can be used to mark an email as unread? I am checking the mail using some IMAP functions that return the messages as read, but I want to make them unread.

Answer 1

To mark an email message as unread, you should unset the \\\\Seen flag on that message.
You could use theimap_clearflag_full function to clear message flags.

// Unset desired flag
imap_clearflag_full($imap_connection, $message_number, "\\Seen");
// Confirm changes
imap_close($imap_connection, CL_EXPUNGE);

Note:

"I am checking the mail using some IMAP functions that return the messages as read"

You can set the FT_PEEK flag when reading messages, this will not set the \\\\Seen flag if not already set.

// This will not mark a message as seen
$body = imap_body($imap_stream, $msg_number, FT_PEEK);
